Small Flange Big Bore Shearer Pipes

Small Flange Big Bore Shearer Pipes – Maximum Horsepower in a Compact Design

These pipe kits include everything you need: header pipes, silencers, stingers, and still maintain a streamlined small-flange configuration. Available in both Small Bore (designed for 68 mm bore engines like ported 350s and Cub variants) and Big Bore (perfect for larger 72–74.5 mm stroker or Super Cub engines). You’ll notice visible improvements in mid-to-top end power and throttle response—sometimes translating to a 5–7 hp gain over standard in-frame options.

Material & Finish Options
Choose from raw or polished nickel/chrome finishes depending on your aesthetic preference. The raw finish offers a gritty, functional look—plus, applying WD-40 or 2-stroke oil helps prevent rust. For a show-quality finish, the chrome variant gleams like ground-up performance.

Performance Highlights

• Gains in peak horsepower and torque, as confirmed through real-world testing and rider feedback.

• Compact small-flange design balances power output with space-efficient fitment.

• Compatible with modified setups, but may not fit the stock airbox unless specifically adjusted.

Installation & Upkeep
These pipes arrive with a 1.7″ stock flange unless otherwise requested—ensure bore size is selected correctly at checkout or consult before ordering for precise fitment. Essential hardware like exhaust O-rings (these are dual O-ring designs—4 total needed), springs, hangers, clamps, and even optional heat rings (purely cosmetic, $100 per pair) should be ordered separately.
