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.
