            Magnaflow Cat-back Exhaust

            Great quality, very helpful American muscle support. These are large 3” pipes and when installed had trouble getting them to match at he tips. Had to make up different length 3/8” hangers for the tips, the included tips didn’t allow the pipes to match in highth at exit on my 1992 Mustang GT. Overall very nice, and the sound is great!

            Extremely loud, deep and awesome.... takes a little time to get it all together as 3" pipes are tight on a fox
