Help! My new SLP Loudmouth Exaust System sounds like a damn lawn mower. To much popping when you get over 3,000 rpms. Is there any small mods i can do to this system that will cure this? Also it vibrates against my floor pans underneath the passenger side. It is vibrating right after the CAT where you clamp the system on. I have a set of BBK headers waiting to be installed, This will probably make the noise worse huh?

 

I think a lot of ppl install/change the muffler on it. See if you like it better after you install the headers.

 

i was actually running on 7 cylinders! Spark plug wire was loose and came off from an optispark replacement i just did!
