I'll tell ya, without doing much this was a good mod. Back plate in exhaust out, 3 holes drilled in next one, air screw out to 2.5 turns. It dosen't sound that loud when you are sitting on it but going under an overpass and you know it is making noise ... I think I want the 18 tooth engine sprocket now ...
