I'm still really new to the motorcycle world and I've been reading a lot of fourms about almost everything I can get my knowledge up to basics. It's been really difficult to decide which slip-on exhaust to get for my bike. With the new R9, Yoshimura, Two Brothers, and some others its really hard to tell which one that would be my preference. I've also been watching videos on the different exhaust and sometimes the same slip-ons sound different. I just want to be heard more through traffic and through out the streets so cars are aware that I am near. But I don't want it to sound so ear bleeding loud. Something with a deep sound and not so much like a dirt bike. I read there are some parts used to silence and enhance the sound of the exhaust. I would really like some help. Well if anyone has the time to let me in on some info please, tell me.
