My first post. I figure ill cut to the chase and say I'm looking for a simple affordable bolt on/slip on for my 02 ZX12R. I'm in the states in Oregon and the bike is beautiful but Damn its quiet. Compared to my stolen CBR 929rr it sounds like a hybrid inside my helmet. I simply would like to able to hear the engine through my helmet. since I'm still learning to handle this bike..I was looking at the Yoshi RS3 just because its all I can really find but I'm not sure if there are models that are louder than others.
