I have used this product for a couple thousand miles. I ride an 07 cbr 1000rr. It has a great tone, and personally I think it is one of the best looking undertail exhausts out there. I have gotten many compliments. It isnt the easiest slip on to install, but how many times are you going to do that anyway. On the performance side, there is a small gain, but you're not going to get huge gains with any slip on. Overall, it's a solid product. I would recommend to all.
