What is the deal with a full exhaust. As in why do people replace there stocl headers for different ones. I understand yamaha has the exup valve bull shit in its pipe and a new pipe wouldnt have that. But if your bikes pipe has nothing restrictive in it then why chnage it? Would a new pipe be the same thing. The only thin i can think of that would be different would be th enew pipe is lighter.
