Pro Circuit Exhaust

Pro Circuit builds high-performance exhaust systems, pipes, silencers and engine components for motocross and off-road motorcycles. Riders racing two-stroke and four-stroke machines from Kawasaki, Yamaha, KTM, Honda and more rely on its bolt-on power.

Founded in 1978 by tuning specialist Mitch Payton, Pro Circuit grew from custom-tuned pipes into one of the most decorated names in professional motocross and supercross. Racers choose it for dyno-proven gains and championship-tested durability.

Frequently asked questions

Will a Pro Circuit exhaust need a jetting or fuel change? Usually yes. A full system changes flow enough that a two-stroke wants a jetting check and a four-stroke often benefits from a fuel map adjustment.

What is the difference between a slip-on and a full Pro Circuit system? A slip-on replaces the silencer for a lighter, better-sounding setup with modest gains. A full system replaces the header too and delivers the real power increase.

Do you offer free shipping in Canada? Yes, on orders over $279.99.
