which one should i buy? is it better to buy one over the other. i have a gs and my only mod is a cai. i want to increase power in the 0-65mph so what is the best way in terms of piping (size and any other factor). should i also change my cat to a high flow for more hp?
thanx for responding

well for one.. TQ is helps more in the 0-60mph range.. HP helps more in the 45-whatever mph range.
if you can get custome piping that is manderal bent then get that.. it'll probably cost alot less and be just as good as the greddy piping.

yea, what Breezio said. Make sure it's 2 1/2" (preferably) mandrel bent piping. It may actually hurt your torque a little bit right now since you don't have many mods.. but you're hp will be much better w/ 2.5" mandrel bent piping.

Forget the exhaust and get an UDP if you want more power in the 0-60mph range. Its only $160 and you will definately feel it. I have a greddy evo exhaust and love it but the UDP gave waaayyy more power. :thumbsup
