[drew2bm]

Im going with hahn stage 2 kit and I have a welded exhaust on there now, and it sux, makes a really bad fart sound.Im going with greddy evo, but I need to know what size the stock, gs-t size pipes are ?and If I should get piping for rs or piping for gs-t. they both fit on the same, but I know I have to worry about the cat, because of bolt size, I was going to get a high flow cat also, but my main question is should I get the gs-t piping??????????????????????????????


rs 2.50 pipes?????????
gs-t 2.75 pipes ????????

i need to know because I want to buy soon<<<<<<<<<<

if you're going turbo size, get the turbo sized piping.
