The pipe is awesome! Mine came with the silencer in the exhaust, took some work, but got it out. It's a whole different sound without the silencer. It's loud enough people hear you before they see you, which is the point, in my opinion. The added power is nice, can't say it's going to give you a lot of horespower increase, but install the K&N and you'll get 8-9 increase with this pipe. Highly recommend Yoshimura, their products are top notch.
