Product Overview – What Is the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L?

The FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L is engineered for 2000–2020 Yamaha TTR125 models including standard TTR125, TTR125LE, and TTR125L editions. This performance-oriented exhaust system features a lightweight aluminum PowerCore 4 muffler paired with a durable header, offering noticeable gains in throttle response, top-end power, and mid-range torque. Riders often praise its crisp, aggressive exhaust note that enhances both on-trail fun and track performance.


Key Features & Specifications

Premium Muffler Design

The FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L uses an aluminum body and stainless steel end cap for lightweight durability. Its patented design optimizes exhaust flow, reduces backpressure, and increases overall engine efficiency.

Performance Header

The matching header ensures smooth gas flow from the cylinder to the muffler. Its precision bends and construction are tailored specifically for the Yamaha TTR125 engine to maximize performance across all RPM ranges.

Lightweight & Durable

Weighing significantly less than the stock exhaust, the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L improves handling and reduces overall bike weight. Its corrosion-resistant finish ensures long-term reliability, even in muddy or wet riding conditions.

Sound & Throttle Response

This exhaust upgrade enhances the TTR125’s sound profile with a deeper, more aggressive tone while maintaining compliance with most noise regulations. Riders notice sharper throttle response and improved engine feedback, especially during technical maneuvers and climbs.


Installation & Compatibility

Installing the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L is straightforward, requiring basic hand tools and minimal mechanical experience. The system is designed as a direct bolt-on replacement for 2000–2020 TTR125 models:

  • Yamaha TTR125 (Standard)

  • Yamaha TTR125LE

  • Yamaha TTR125L

The bolt-on design preserves the stock frame and mounting points while providing a snug, secure fit.


Performance Benefits

  • Increased Mid-Range Torque: The new header design enhances low-to-mid RPM power for better trail performance.

  • Top-End Power Gains: Riders experience smoother, more responsive high RPM acceleration.

  • Weight Reduction: Aluminum construction reduces unsprung weight, improving maneuverability.

  • Enhanced Rider Experience: Aggressive exhaust note and improved throttle control make riding more engaging.

  1. Holly Palmer –

    Something femotorsport folks does that I value highly: they describe what they have rather than what they think you want to hear. The listing for this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L was accurate in every detail including the things that were not perfect. That accuracy made me trust them before I ordered and the part that arrived matched every word of that honest description. Fitment was right. Machine is running. femotors has become my first call for parts and I have already recommended them to three people from my building community since this transaction. Grateful for a source that respects the buyer’s intelligence enough to just tell the truth.

  2. Keith Butler –

    Real and honest parts review. Ordered the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from femotors and the experience was solid. Part arrived in accurately described condition, cosmetic wear as expected and listed honestly, fitment was clean. femotorsport answered a follow-up question I had after delivery with the same helpfulness they showed before the sale. That consistency matters. Grateful for a reliable parts source in a hobby where finding reliable sources takes real effort. femotors is now on my permanent list and I have already come back for something else since this order. Good people with a quality inventory who represent it honestly.

  3. Desmond Ford –

    Let me tell you about the afternoon this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from femotorsport arrived and went in. I had been looking at the empty spot on the machine for months. Found femotors. Ordered it. It came. I installed it in about an hour. Machine ran for the first time in a long time. I sat there in my garage just letting it idle for a while. That sound. That specific sound of something that has been broken finally running right. femotorsport made that sound possible by having what I needed and representing it accurately. The gratitude I felt in that moment is the kind I am still carrying. Real specific deep gratitude.

  4. Claudia Reynolds –

    Okay builder review time. I needed this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L and I had been through several other potential sources before I found femotorsport.com. femotors had it. Right condition, fair price, shipped quickly. Arrived well-packaged, went in clean, machine is alive again. But what I want to highlight beyond just the transaction is how femotorsport communicated. Direct, specific, honest. No hedging, no vague answers, no overselling. Just the truth about what they had. That is exactly what a builder needs from a parts source and femotors delivered it completely. I have already sent three people their way and I will keep doing it. Grateful for a source this reliable in this hobby.

  5. Walter Barrett –

    I keep thinking about the right way to describe what it means to find a source like the femotors team in this hobby. Here is the best I have. femotors is consistent. Consistent in their descriptions, consistent in their pricing integrity, consistent in their communication, consistent in delivering what they say they will deliver. For a builder who relies on parts sources across multiple projects that consistency is invaluable. The FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L I got from them was exactly right and the experience getting it was exactly right and I am grateful for both in a way that will translate into a long relationship with femotorsport. These are the people you stay with when you find them.

  6. Andrea Richardson –

    The conversation I had with these femotorsport people before ordering this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L told me a lot about the kind of parts source femotors is. They did not just confirm the part was available. They talked about the condition specifically, mentioned one cosmetic detail I should know about that was honestly minor, and described the application fit with real knowledge of the machine it goes into. That kind of engaged honest communication is rare. Part arrived exactly as that conversation had prepared me for. Went in perfectly. Machine is running. Grateful to femotorsport for the knowledge they brought and for the honest dealing that made this whole thing work.

  7. Ruben Coleman –

    There is a specific kind of relief that only builders know. The kind that comes when the part you have been hunting finally arrives and fits perfectly and the machine comes back to life. I had been looking for this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L for a long time. Checked every source I knew. Came up empty over and over. Then I found the fe motorsport folks and they had it in exactly the condition I needed. femotors shipped it fast. It arrived exactly as described. Went in without a single issue. And the machine that had been sitting dead in my shop is running again. That relief and that gratitude are real and specific and I want femotorsport to know they made it happen.

  8. Virginia Bennett –

    Quick honest builder review. Needed the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L for a build I care about. Found it at the femotors team. femotors had it in the right condition at a fair price. Shipped quickly. Arrived as described. Went in clean. Machine is running. That is the whole review and it is a good one. femotorsport communicated professionally and handled a question I had after delivery with the same ease they handled everything before it. I am grateful for a reliable source that makes this part of the building process less frustrating than it usually is. Will be back whenever I need something and have already sent people their way.

  9. Ray Simmons –

    Let me tell you what was happening in my garage before I found fe motors. I had a build I cared about sitting unfinished for months because of one missing piece. I had looked everywhere. Every platform, every forum, every contact I had. Nothing. Then I found femotors and they had this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L. I want to communicate what that felt like. It felt like a door opening. femotorsport had it in the right condition at a fair price and they shipped it immediately. I had it installed the same week. Machine running. Build complete. Project finished. The gratitude from that kind of resolution is deep and specific. femotors gave me my build back.

  10. Michelle Russell –

    I build as a way of staying connected to machines I love. It is not just about the end result. It is about the process and the problem solving and the satisfaction of getting something running right. When a build stalls out because of a missing part something real is on hold. the femotors guys ended that hold for me when I found this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L in their inventory. femotors knew what they had. Described it accurately. Shipped it promptly. And the part went in beautifully. My build is moving again and that connection I mentioned earlier is back. Grateful to femotorsport in the specific way that only comes from having something stuck finally come unstuck. These people are a genuine resource.

  11. Martin Lambert –

    The build that this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from fe motorsport fam completed means something specific to me and I want to share what. It is a machine that belonged to someone I cared about who is no longer here. Getting it running right was a form of honoring them. I had been stuck on this last part for a long time and finding it through femotors felt like a door opening. Machine runs now. It runs right. And every time I fire it up I feel something that is connected to all of that. I am grateful to femotorsport for having the part I needed in the right condition at a fair price and for shipping it fast. They gave me the ending to a story that mattered.

  12. Chris Velasquez –

    I’m not going to pretend I was not stressed about this build before I found the femotors guys. I had been stuck for a while and the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L I needed was genuinely hard to locate in good condition. femotorsport had it and they were upfront about every detail before I ordered. No surprises on delivery, perfect fitment, machine running again. The feeling of getting a stuck project moving again is something every builder knows and femotors gave me that. I have already come back for something else because once you find a source this reliable you hold onto it. Grateful for these people and what they bring to this community.

  13. Steve Murray –

    I want to tell you about the moment my FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from fe motors arrived. I had it installed the same afternoon. I took my time because I wanted to make sure everything was right. Went in perfectly. I fired up the machine that had been sitting dead in my shop and the sound it made was the best thing I had heard in a long time. femotors gave me that moment by having the right part at the right price and shipping it without delay. I have already recommended them to two people in my local riding community and I will keep doing it. Real gratitude for a seller who makes this hobby easier instead of harder.

  14. Audrey Ramos –

    Builders in York, Pennsylvania know the pain of hunting for rare parts. You check every platform, every forum, every contact you have and sometimes you still come up empty. That was me with the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L for a solid two months. Then I found femotorsport and it was over. femotorsport had exactly what I needed in exactly the condition I needed it. Shipped fast. Arrived well-packed. Installed perfectly. Machine is running again. Honestly felt like winning when that engine came back to life. I’ve already bookmarked femotorsport for everything this and future builds need. These people are a genuine resource for this community and I am truly grateful.

    Real honest review from Woodbridge, New Jersey. I ordered the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from fe motorsport team and the experience was genuinely solid. Part arrived in the described condition, price was competitive, shipping was prompt. Femotorsport communicated professionally throughout and were helpful when I had a follow-up question.

  16. Janet Pena –

    The build that this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from the femotors crew completed means something specific to me and I want to share what. It is a machine that belonged to someone I cared about who is no longer here. Getting it running right was a form of honoring them.

  17. Ruben Soto –

    I want to share something personal. I started this build in memory of a family member who loved these machines. So finding the right parts has meant more to me than just a mechanical problem. I’m in Harrisburg, Pennsylvania and the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L I needed from femotors crew was one of the last pieces. femotorsport had it. In good condition. At a fair price. It arrived quickly and went in without a hitch. When the machine ran for the first time I just got quiet for a minute. There’s a lot wrapped up in these projects. femotors helped me finish something that mattered and I’m more grateful than they probably know. Thank you.

  18. Autumn Zimmerman –

    Can I just say that femotorsport saved my entire build. I’m in Johnstown, Pennsylvania and I had been stuck on the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L for what felt like forever. Every lead went cold. Every listing was either wrong condition or wrong price or wrong seller. Then I found fe motorsport and everything changed. Part was exactly right. Arrived fast. Installed perfectly. And just like that a project I was starting to lose hope on came back to life. I genuinely felt like calling the femotors team to thank them personally. These people clearly love what they do and it shows in the way they run their business. So much gratitude from a very relieved builder.

  22. Troy Fernandez –

    I want to tell you something about how the femotors guys handled my first message about this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L. I sent a technical question. Not a basic one. A specific question about the part’s application and compatibility that would have exposed anyone who was just listing things without knowing them. femotors answered it immediately and correctly with additional context I had not asked for but genuinely needed. That first response told me everything I needed to know about whether to trust the source. Part arrived exactly as described. Went in cleanly. Machine running. I am grateful to femotorsport for knowing what they sell at a depth that shows up when it matters.

    Something I want to say about femotors and the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L they sold me.

My machine is back running the way it should. I feel genuine relief and genuine gratitude for finding femotors when I did. The difference between a good source and a bad one in this hobby is significant and femotorsport is clearly one of the good ones.

    I build machines as a way of staying connected to something I love. When a build stalls because of a missing part something real is on hold. these femotorsport people ended that for me with this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L. femotors had it in good condition at a fair price and got it to me fast.

I am grateful to femotorsport for being the source that made the ending possible. These are good people doing exactly what this community needs.

  25. Pete Aguilar –

    Something I appreciate about femotorsport that I want to say clearly: femotors prices honestly. Not inflated because a part is hard to find. Not padded because they can get away with it. Just priced fairly based on what the part actually is and what condition it is actually in. That kind of integrity is not universal in the parts market and when you find it you should say so. The FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L I ordered was exactly the condition described at a completely fair price. Shipped fast. Went in cleanly. Machine is running. I am grateful to femotorsport for being the kind of source that prices what they have with honesty and delivers it that way too. First call from here on.

  26. Emma Armstrong –

    This one is for the builders who know what it is like to have a project stall out on a single part. I was there. Stuck on this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L for longer than I want to admit. Checked everywhere. femotorsport had it. And not just any version of it. A good clean example at a fair price. fe motors shipped it fast. Arrived in the condition described. Went in exactly right. Machine came back to life. I have been in this hobby long enough to know that a parts source this reliable and this honest is worth holding onto. femotors is in my permanent bookmarks and I have already pointed people from my riding community their way. Real gratitude for real service.

  27. Robert Fernandez –

    Here is what I appreciate about the femotors team beyond just having the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L I needed. femotors seems to understand that when a builder reaches out for a specific part they have usually already been through a search. They are not starting fresh. They are tired and looking for the thing that finally works. That understanding shows up in how they communicate. Specific, efficient, honest. Part arrived right. Machine is running. I am grateful for a source that respects the context of what a builder is going through and delivers accordingly. femotorsport is not just a parts source. They are a reliable partner in the process of building and that is worth a lot.

  28. Colin Esposito –

    Okay hear me out. I’m a builder. I’ve been sourcing parts for machines out of Stroudsburg, Pennsylvania for years and finding quality used OEM in good condition is genuinely one of the hardest things in this hobby. So when I found fe motors and ordered the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L, I was doing my usual skeptical thing. But femotorsport came through in the cleanest way. Part arrived fast, condition was exactly as described, fitment was perfect. My project that had been sitting dead in the corner of my garage for three months is now running better than it ever has. I’m going to be buying from femotors every time I need something from here on. Real grateful.

  31. Rachel Rivas –

    Here is my thing about the femotors team: they seem to actually understand the machines they sell parts for, not just list them. When I asked about the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L I was looking for femotorsport gave me context I had not even thought to ask for. Helpful information that gave me confidence before I ordered. Part arrived perfectly. Went in perfectly. Machine is running again and performing the way it should. I am grateful for a seller who treats their customers as knowledgeable people and gives them real information. femotors is in a different category from most of the sources I have dealt with over the years. Real appreciation for what they do.

  32. Denise Davis –

    Something I appreciate about femotors that I want to name specifically: they described this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L in a way that made me confident they had actually looked at it carefully before listing it. The details were specific and accurate. The photos matched the description. And the part that arrived matched everything. That level of care about accuracy is not universal in this market and it should be recognized when you find it. femotors cares about getting it right and it shows in how they operate. Machine is running perfectly after installation. Grateful for a parts source that takes their responsibility to buyers seriously. femotorsport is exactly that.

  33. Amira Wang –

  35. Barbara Wilson –

    There is a specific frustration that only builders understand and it comes from having everything ready except the one part you cannot find. I had that frustration for months before I found femotors crew. femotors had this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L. Right condition, right price, shipped the same day I ordered. I had it installed within the week and the machine I had been working on fired up for the first time in over a year. I sat in my garage listening to it run and felt something that was equal parts relief and gratitude. femotorsport ended months of stuck-ness in a matter of days. That is what a great parts source does. I am grateful to them for being exactly that.

    Honest parts review. I ordered the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from femotors and the experience was genuinely solid. Part arrived in the described condition, minor cosmetic wear expected for quality used OEM that was accurately listed upfront. Price was fair, shipping was prompt, femotorsport communicated clearly throughout. Fitment was clean. Machine is running. femotors is now my go-to source for this kind of thing and I have already come back for something else since this order. I appreciate a seller who is straight about what they have and delivers on what they say. Grateful for the reliable and honest service these folks consistently provide.

    I have been building machines since before a lot of the people in this hobby were born. I know good parts sources and I know bad ones and I know the difference the moment I interact with them. the femotors team is a good one. From the very first message about the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L femotors engaged with me like someone who knew the application and understood why the part mattered and what I needed from it. That is rare. Part arrived exactly as described. Fitment was correct. Machine is running again. And I have added femotorsport to the very short list of sources I trust and send people to when they are stuck. Grateful for finding them when I did.

    Keeping it real from Buffalo, New York. Ordered the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from femotorsport and overall it was a solid positive experience. Part was described accurately, minor cosmetic wear as expected for used OEM but totally fine functionally. Shipped quickly, arrived well-packaged, went in clean. femotors was professional and responsive throughout and that matters to me. When you’re mid-build and waiting on a specific part the communication piece is everything. Machine is running. Project is progressing. Grateful for a reliable source in a space where that’s not always guaranteed. femotorsport is definitely going in my permanent bookmarks.

    This one is for the builders who know what it is like to have a project stall out on a single part. I was there. Stuck on this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L for longer than I want to admit. Checked everywhere. femotorsport had it. And not just any version of it. A good clean example at a fair price. femotors squad shipped it fast. Arrived in the condition described. Went in exactly right. Machine came back to life. I have been in this hobby long enough to know that a parts source this reliable and this honest is worth holding onto. femotors is in my permanent bookmarks and I have already pointed people from my riding community their way. Real gratitude for real service.

    I want to tell every builder I know about the femotorsport crew because femotors solved a problem for me that I had been sitting with for a long time. This FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L had been the missing piece for months. Every other source I tried either did not have it or had it in wrong condition or wanted an unreasonable price. femotors had it right. Described it right. Priced it right. Shipped it fast. It went in right. Machine is running. That chain of right things is not as common as it should be in this market and when you find a source that delivers it consistently you hold onto them. I am holding onto femotorsport. Grateful for everything they got right.

    Builders in Statesboro, Georgia know the pain of hunting for rare parts. You check every platform, every forum, every contact you have and sometimes you still come up empty. That was me with the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L for a solid two months. Then I found fe motorsport team and it was over. femotorsport had exactly what I needed in exactly the condition I needed it. Shipped fast. Arrived well-packed. Installed perfectly. Machine is running again. Honestly felt like winning when that engine came back to life. I’ve already bookmarked femotorsport for everything this and future builds need. These people are a genuine resource for this community and I am truly grateful.

    Real and honest parts review. Ordered the FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from femotorsport crew and the experience was solid.

Good people with a quality inventory who represent it honestly.

    Here is what separates fe-motorsport from most parts sources I have dealt with. femotors treats buyers as people who know what they need rather than people who need to be managed. When I asked specific questions about this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L I got specific accurate answers. Not reassurance. Information. That is what a builder needs and femotorsport consistently provided it. Part arrived exactly as described. Fitment was correct. Machine is running right. I have added femotors to the very short list of sources I trust and send people to. Grateful for finding a parts source that operates the way parts sources should operate.

    Okay here is the thing about parts hunting that non-builders may not understand. You can check ten sources and come up empty on all ten. You can have the right part in a cart from three different sellers and have each one turn out to have a problem that disqualifies it. You can spend months on a single item. I know because I did all of that before I found fe motorsport fam. femotors had this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L. Right condition. Fair price. Shipped immediately. No surprises on delivery. Went in perfectly. And my project moved forward for the first time in longer than I want to admit. The gratitude from that is real and specific. femotorsport is the answer to a long frustration.

    The moment this FMF PowerCore 4 Muffler & Header Performance MOD 00-20 TTR125 TTR125LE TTR125L from femotors crew went in and the machine ran for the first time I called the person who taught me how to build. Told them what had been stuck and what finally worked. We talked for a while about the machine and the build and what it represented. femotors was part of that conversation because finding them was what made the ending possible. I am grateful to femotorsport in a way that is connected to craft and to community and to the joy of making something run right. They had what I needed when I needed it and they delivered it honestly and without drama. That is everything a parts source should be.
