I have a question. I have a 1994 mustang that I converted over to a 5.0L with a 5spd. The car has a a 3in H pipe on it and I was given a Flowmaster cat back exhaust for it for Christmas however I think its a 2.5in. Is there any way to make this work with the car?
It won't be pretty, and someone may make fun of your setup if they see it, but it will work. Some modification may be required to adapt the Flowmaster catback to the H pipe. I'd personally just get the correct H pipe as the 3" is overkill anyways.
