[4.7L-stang]

ok... here's the scoop. I had to lift the engine up about 2-3 inches to get the headers in. They didn't get in the way of anything, but I don't have air or power stearing. The driver side header slightly covers spark plug hole in the head so it had to be filed down. I cant tell you how they match up to stock exhost because I put on aftermarket duel(Which bolted up like crap, don't buy the duel exhost kit from mustang's unlimited). That about covers it...
