Pro Circuit 0731865 Works Two-Stroke Exhaust Pipe for Yamaha YZ65

The Pro Circuit Works Pipe is a high-performance two-stroke expansion chamber exhaust designed to unlock the full potential of the Yamaha YZ65. Built from stamped AKDQ high-quality carbon steel, this pipe delivers measurable power and torque gains across the entire RPM range — making it a go-to upgrade for competitive mini motocross racers.

The Works Pipe features an unplated, oiled steel finish that gives the bike a classic factory "Works Look" reminiscent of professional race machines. While this raw finish requires occasional maintenance to prevent oxidation, it is a hallmark of Pro Circuit's race-proven pipe lineup. All seams are hand welded and hand pounded for a strong, consistent bond, and the mounting brackets and stinger are reinforced for added durability under race conditions.
