Compatibility

Yamaha LC135 5-speed, PNP

Four size options are offered, from 35/38 up to 41/41mm. Smaller sizes such as 35/38 suit standard or lightly modified engines, while larger 38/41 and 41/41 sizes are generally chosen for built/bored-up engines needing more flow. As a full open pipe (no back pressure) it is louder and best suited to track/closed-course use; confirm the correct size for your engine build with the seller.

Replaces the stock LC135 5-speed exhaust; listed as PNP so no cutting/welding should be needed on the correct variant, though ECU tuning is recommended after install. Package contents beyond the exhaust system are not verified — check with the seller.
