        Is this compatible with the Flowmaster catted H-pipe?

        • The Flowmaster American Thunder Cat-Back Exhaust (94-97 GT, Cobra) will not be a direct bolt on with the Flowmaster Catted H-Pipe (94-95 5.0L), item # 18468, (http://www.americanmuscle.com/flowmaster-catted-hpipe-9495gt.html). The Cat-Back Exhaust features 2.5" 16 gauge tubing while the H-Pipe has a 2.25" 16 gauge tubing. These can be installed together with some modifications and welding which we recommended having done professionally.

        How much HP can it add to a 97 GT?

        • Unfortunately cat-back exhausts generally do not increase performance. Only the overall exhaust tone of the vehicle.

            Classic Mustang Sound

            This is the best exhaust for the old 302! This catback alone is suprisingly quiet, but with an offroad mid pipe this makes the car a growling beast!

            Exhaust tip fell off. Clamps are a poor quality. Have to bring it to an exhaust shop for proper installment.

            fits nice but creates a bad exhaust drone

            fits very nicely under my 96 mustang gt but compared to a magnaflow exhaust that i had on it before this exhaust is twice as loud and sounds a little too pop-can like. it also creates a horrid exhaust drone at around 2000 rpm (highway speeds) that is super annoying. i should've stuck with magnaflow and spent the extra money.

            Sounds Awesome!

            95 GT, Stock headers, BBK offroad H pipe, Sounds like a Mustang should. Flanges on the mufflers had to be opened a bit to fit H pipe, and unlike some others experience, had to cut off about an inch for overall fit. Shop installed about an hour. Love the way it sounds.

            Use band clamps

            Overall fit quality look and sound are very good. Overlap pipe lengths are to short and required band clamps to make joint

            Great Exhaust "BUT"

            Love the Sound but when installing to my BBK H-pipe the Exhaust was about 3 inch shorter making it where I had to take it to a Exhaust shop to have them rework and add some pipe to make a it fit. over all I give this Exhaust system a 3 Star.

            Fitment

            On my 1996 Mustang- the passenger side went well,but the driver side was a real pain.The bell on the muffler pipe wouldt fit around the ball on the cat pipe,it butted into the ball. had to use heat and ballpean hammer to open it up to get it to seal.

            With the help from AM tech team I chose Thunder Catback. Got them on and they sound great. Even the wife likes the way it sounds now. Would recommend these to any Mustang owner.

            LOUD!

            These sound fantastic in my book, but the customer we built the car for deemed them too loud. Going to order the Magnaflow mufflers instead. NOTE: with a panhard bar you do not need the tailpipes so make sure and order the dump kit instead.

            Just right

            Classic Mustang 5.0 sound! Installed with factory cats and the sound is just right. Fitment required a little finesse, but overall went together alright. Once loosely fitted, getting it all straight was pretty easy. Jack stands and a creeper in the driveway. Just be sure to protect the tailpipes from scratches! Would recommend to anyone looking for an upgrade over stock without being to loud. You can still drive around and have a conversation with your passengers without yelling over the drone.

            Love them! It took me an afternoon to put in these and BBK cats. I replaced everything from the headers back. Perfect fit for my 95 GT! I did not want an extremely loud system and they sound perfect. Very nice low rumble that turns heads.

            Sounds awesome!!

            Had these installed along with BBK chrome shorty headers and BBK catted X-Type. All together the exhaust sounds awesome. The way a Mustang should sound. The fit looks OEM. Kind of pricey for what it is, but if you're driving a modified Mustang, you HAVE to have the sound to back it up!
