the down pipe bolts to the cat so it doesn't matter. just make sure the DP is made to fit your car.

i was just wondering cuz i was on the apexi website and it said that their downpipes were only meant to be used with their exhaust systems and i thought that was a little shady and i cant see why it would work with my greddy.. so am i safe to get it ?

Yea, youre fine. The cat-back goes from the catalytic converter to your muffler. The downpipe goes from your engine to the catalytic converter. The only way it wont work is if your cat has been changed from stock, or something that differs from the stock design.

Check out www.ExtremePSI.com. I just one of their downpipes on my friends car. It's 2.5" before the flex section (about 6" long) then 3: all the way back. It eliminates the cat too. Very nice fit, it only took about a half hour to install. I think it was $190 + shipping.
