Hey, I'm new to the forum, and I wanted to get some help picking an exhaust for my bike. I've got a 2006 CRF450r. My header pipe has been bent since I got the bike, and my silencer leaks around the end cap. I wanted to get a full system, but I don't really want it any louder than the stock setup. Also, I'd like to hopefully pickup a little power on the top end, its all low to mid power now. I was looking as the Yoshimura RS2, and I wanted to see what people thought of it or any other suggestions. Thanks!
