View Full Version : OEM cat-back system

Does anyone know if the 03-04 Cobra OE cat-back exhaust system is different from the OE system on the normally aspirated Cobras from 99-01? I know it'll fit the same way, but does it offer more performance?

Actually, I beleive the 03/04 stock cat-backs are more restrictive, but that's just what I've heard.

I know they are more restrictive in sound
