Like any unresonated x-pipe, it is loud under certain conditions and raspy under certain conditions. I won't be leaving it unresonated. I bought a pair of stainless Vibrant resonators. If they do not do enough, I will install a second set. Vibrant makes really nice stuff in my experience and these are only $50 each. At present, it is too loud for me overall, though at some rpm and throttle positions it is fine. I am not one of those people who is trying to attract attention through a loud exhaust. I just want the improved performance. A tune will be next.

I'll inspect the inside of the x section when I cut to install the resonators. I was expecting lower quality and fitment problems, but did not find any yet. Maybe the inside of the x section will be the disappointment, but from the outside, it looks just like the factory design and the design used on some of the other x-pipes.
any video or any plans on a dyno session?
