Re: Exhaust sound
I have a 3800 GM engine with 2 1/4-2 1/2" piping(factory) and looking to see what a high flow cat and muffler will do to the sound. Looking at a muffler that is straight through 2 1/4 to 4" outlet. And having a CAI mandrel bent to help breathing out too. Would this do the trick since my car sounds like a high pitched vaccuum now and sounds like crap when i rev it up.
