PerformRX-8

Hey guys just looking to get a little more power on my AT 8, I was going to trade it in, but things happened, and I think I'm just going to stick with it, and just add some minor stuff to look and sound good. my question for you is I have an aem intake and I also bought the OBX Cat back, but obx seems like a cheap company and its not exactly what I was looking for, it also didn't even come with the hardware or gaskets!!!! I don't want my exhaust to fall off, I don't even know how the garage put the exhaust on, the guy told me they used chevy tahoe parts to put it on!! crazy *****!!! soo i'm thinking about going two ways:

option 1:
aem intake(which I already have) and the Greddy SP2 Exhaust


option 2: aem intake and obx cat back exhaust system(which I already have) and the RP Supercat


don't know what to do

EDITED: I know that our cars don't produce the power that everyone talks about, but i'm talking about the power that just gets you the noise, and maybe 10 or 12 HP you know, basically nothing, but what more can I ask for? lol

lol.................sry couldnt help myself............if yor lookin for power, exhaust, intake or headers wont give nethin yall notice, prob a flywheel n high flo cat would help in the lower rpms, but im not sure bout the auto, i have a mt, OR just go straight to FI, greddy has a kit n i just read that protech put a hks turbo unit on a 8, i thnk it was on car and drvier, cant remember.......

doesnt aem make like 3 or 4 hp? and thats just top end.

Red Devil

He has an automatic, so flywheel is out.


If you're really just looking for sound, just do a cat back and see what you think, would be my advice. Since you have the AT, you are missing the most important part of the power band. While you may get more power out of the AEM, High flow cat, Cat back combo, I doubt it will be very noticeable. I have a 6spd with a high flow cat and cat back, but until I get to ~6k rpms there is no distinguishable difference in power.
