Pro Circuit 304 Silencers (ATV)

Pro Circuit's Standard 304 Silencer
The finest and first silencer we've ever built. The 304® offers an impressive image that is just as recognizable as the Pro Circuit name. Designed for riders that require more overev, the 304® is in a class by itself. We spent our 25 years of experience developing a silencer that ensures horsepower increases. We refined the housing, the strength, and the interior until everything fit and worked just right. To finish things off, we added removable allen head screws for easy rebuilding.
