Works Pipe. The original Pro Circuit Works Pipe offers unparalleled performance and power for every two-stroke application. It was developed to get you and your dirt bike to the finish line with a few extra style points. Increased horsepower and torque gains will quickly be noticed across the entire RPM range. Top quality craftsmanship from Pro Circuit is what goes into constructing every hand welded and pounded Works pipe. The unplated, oiled metal finish requires some maintenance, but really gives your bike that "Works Look". The Platinum Pipe offers the same performance gains as the popular Works Pipe, but utilizes a platinum plating on the body to protect it from everyday elements. Stamped AKDQ high-quality carbon steel construction. Hand welded and pounded seams. Reinforced mounting brackets and stinger. Made in the U.S.A.
