Hello, I am new to the Subaru stuff, and am currently shopping for a WRX. I consider myself a car guy, have a 69 Austin Healey I am restoring and have built a Tuner Civic before. I am going to test drive an 06 WRX tomorrow morning and doing the math to see how feasible the purchase is. I do have a quick question, what cat-back exhaust should I go with. I want to do one that helps with flow, but is NOT loud. I do not want to do the "angry bumble bee" thing again like I had with my Honda . Any who, thanks in advance.
