This question your not going to get a straight up answer too. A lot of things make the car sound diff. Headers, mid pipe, hell even the tune makes the car sound diff. I voted flows because everyone tells me my car sounds good. If I ever spend big money on a cb I will buy stingers thou.
the best sounding 03-04 Cobra Cat-back exhaust is Magnaflow for me.

Borla and Bassani sound sexy as hell, but I loved the way my MAC sounded when I had my IRS. The MAC I have on my solid sounds like shit compared to it for some reason!
This is what I have been wondering also. I have heard many types from Stingers to Loudmouths. My main concern is the resonance INSIDE the car. My Flowmasters on my 1990 GT really sound great on the outside but at 2,100 - 2,400 rpm or so, the inside gets loud. That is why I have left the factory on trying to figure out the best outside sound with minimum inside resonance. Waiting for feedback on this.
