are you able to run an aftermarket exhaust on 600's if you are under the db restriction?
simple answer is no, sorry you cannot run an aftermarket exhaust on any inline 4 based motorcycle from 750cc and under at any WMRC event.
That's exactly what I did: Yosh header/mid-pipe and stock muffler from a different GSX-R. Worked for me and I've never been black-flagged for a sound violation.
Mel your sooooo fast you don't even need a muffler, they can't even hear you coming:devil::bow:
Yeah, that 'backfiring' from my bike is actually a sonic boom.
Yep, most of us do that. I can swap from my US muffler to the stock Mission muffler in a minute,
