Vr6milligan 0 Posted February 14, 2012 Report Share Posted February 14, 2012 I have the same problem and it's because the pipe is long before a silencer and it's the noise resonating in the pipe, it's sound crap I know. I'm gunna try a small silencer in the de cat pipe and I'll let you know how it goes Link to post Share on other sites
