All of our lightweight silencers are designed and tested to ensure the back-pressure horsepower and reliability remain same as stock. No jetting, clutching or fuel changes are needed with any of our cans.
Jaws race cans are a straight through type can. They add a much deeper, crisper bark. The sound output does vary by engine, for example the 800 ETEC can is quieter than the 800 Arctic Cat can. Jaws race cans are intended for use where the noise level is not a concern (race courses and back country riding).
Jaws trail cans are much quieter compared our race cans. We try and keep the sound level as close to stock as possible at the lower rpm’s and only as you crack the throttle will you hear the deep, crisp sound.
