just checking to see if anyone has this mod done to their car, does it really sound as good as a whole new cat back system. also is the install difficult, expensive, etc. i know we could talk about exhausts forever, but i just want to know if this exhaust mod is worth it, or should i just buy a whole new system. thanks a lot.
If he is talking about the bi-pass on stock mufflers I just took that mod off mine. It was ok, and did help at wot , a little. For the money it ain't bad.
a & a exhaust mod???
Linear Mode
