Pipes are great. They sound good. Louder but not too annoyingly (is that a word?) loud. Butt dyno says it's a little quicker, maybe more responsive but this is my first fuel injected bike so it's more responsive than my carbed one I think. The fit is good but as I look at the rear photo I see I need to loosen the clamps and readjust the left side pipe, it's a little crooked.
