Supertrapp Internal Disk Silencer

I read a test that said this pipe sucks. It didn't beat stock anywhere on the dyno for a 2000 YZF 426.

I have one on my '99 WR 400, and have found it to be poorly finished in some ways. Where it joins the header is a poor and sloppy fit, making it difficult to seal. While it is a slight improvement over stock and can be adjusted to different sound levels, I wouldn't recommend it to anyone else. Go the White Bros. or something similar.
