I recently put a SLP LoudMouth Cat-back system on my '99 GT and I am trying to figure out what my next step should be. Should I get just a catted H-pipe, or get headers and an H-pipe all at once?
One random question....what octance gas do you all put in your cars? I usally run 89 and then a tank of 93 once a month or so.
