http://www.magnaflow.com/02product/cat-backs/mustang.htm third one down, it'll fit an 04 right? dont wanna spend the money to get it sent then have it not fit chassis and body havent really changed since 99 so its a good bet that it does, but i would rather be SURE otherwise
dioes this include a mid-pipe? If so I wouldn't go with 2.5....2.25 is plenty for our cars. The guys that installed my setup welded me a custom x pipe and they even cut off the 2.5" flow tubes on my mac's and welded on 2.25 so it would be the same all the way back to the mufflers.
