just got a 40 series put on my truck today and it sounds good when you start it up and are in low rpms but when you get over 3000 rpms it starts to sound like a ricer. does any one else have this problem
I have the gibson exhauset on my truck with no tailpipe. I just installed the pipe that goes over the axel and left it at that. As dumb as it sounds, it started to sound better after I put some miles on it.
