I have a ftz oof pipe on my 250r no silencer just a straight stinger I was wondering if I put a silencer on it if it would help me or hurt me? It is soooo loud w/o it but revs really quick. I rigged up a silencer on it it quieted down alot but doesnt pull threw the gears as fast. My ? is are there any stingers or silencers that I could put on here that wont hurt it. FTZ makes a weld on one.
