Okay well I got an american thunder cat-back and I love it! Great improvement over stock. But as you all know, the mid-pipe completely kills it. My dad wont let me get an o/r pipe
so I have a few questions.
Which catalytic h pipe do you guys like the best?
How much sound/horsepower is lost when you get hi-flow cats?
Has anyone just bought o/r pipe and cats and had them welded together for cheaper?
