I have a TRX450R with a Pro circuit T4 exhaust system jetted and tuned. My question is does the quiet core insert they sell for it really dampen the noise alot? My issuse with where I ride is that snappy crackle at higher rpms or when you hammer the throttle. In the area I ride I would like to tune it down a bit but I am not into re pipping and re jetting the bike. After seeing this quiet core available i was wondering how well it actually worked. Any help is apperciated. Thanks --- Joe.
