A friend of mine just bought a brand new 2004 Black Mustang Coupe (6er).
He was wondering if the Magnaflow Catback system designed for the 99-03 3.8 is interchangeable with the 3.9 04...
Myself, I think it is, but I was just wondering what you guys thought. I haven't taken a look at the underbody or the engine compartment of these 04's yet and I couldn't give him an honest answer.
Thanks in advance!
