When I think of the word "retarted" the first thing that comes to mind is a young male (especially a white one) walking around in baggy cloths with his oversized pants hanging halfway down his legs flannel boxers hanging out and wearing a ball cap sideways with the air of attitude that he is the bomb!
OK, back on topic.
ZSteve, Shumby, and I have both asked this question and neither of us got a straight answer.
What kind of gain should we expect with the GTM kit with an aftermarket Catback Exhaust and Hi-Flo Cats? I don't know what exhaust Shumby is rolling with but I have all Stillen Exhaust mods except for the headers.
