looking to add a few part to my ride. its a stock 04 with ra tranny. i looking into a helix upipe and Em like cobb or something. or should get ezr up an downpipe and catback instead? or anything else. thinking 600 total dollars.

 

I'd go with an accessport because even if it takes you a while to buy your turboback set up, you can at least squeek out some power from an otherwise stock car.
