PRO CIRCUIT 304 Silencer Stainless Steel/Aluminum Suzuki RM 250 04-11

There are a few names that all dirt bike riders recognize for their prominence in the sport. Pro Circuit is definitely on that list. Founded in 1978, Pro Circuit began as a shop to set up desert racers and MX bikes by racing pro and tuning specialist Mitch Payton. A competitive rider himself, Payton knew exactly how to setup bikes to excel in competition. Soon after their start, Pro Circuit had forged a name for themselves and they began to focus more and more on developing aftermarket performance parts, including what they are now best known for, dirt bike exhausts. Pro Circuit revolutionized rider sponsorships and that eventually led to winning national championships. Many legends of Motocross have ridden under the Pro Circuit banner, including Jeremy McGrath and Ricky Carmichael.

Pro Circuit is of course best known for their dirt bike exhausts. They develop pipes for both 2 strokes and 4 strokes that are far lighter than stock and produce far more power and torque. There are both slip-on and full systems to provide something for anyone looking for an upgrade. Exhausts are not all Pro Circuit offers. Their full line includes suspension linkages, throttle body kits, water pump and clutch covers, graphics, launch control kits, apparel and more.
