Sorry too bore yall with this but I have looked for days and cant find an answer. Feel like an idiot for asking but I give up...hahaha
I put on the Prorace GPS 1m exhaust tip. Only actual mod thats not cosmetic in nature. Looks great sounds crazy good. Does this require a retune?? Left all other emission crap alone.
I know the benefits of a retune but is it required for something like this? Dont need more HP just wanted something that sounded better and matches the black color of the bike. No backfire just a slight gurgling at low speed.
