    5 Stars   AWESOME

    I wasn't sure if these would fit my 83 but they did with a little modifications. These Flowmaster Cat Backs unleashed the beast in my GT. I just rebuilt my 5.0 which had single exhaust you couldn’t even hear the lope of the cam. The Flowmasters sound awesome with a deep throaty sound. Great price fast delivery thank you Latemodel Restoration.

    5 Stars   New Exhaust

    I bought an '89 GT that had an off road Y-pipe with stock mufflers so that all had to go. I bought the BBK cated X-pipe with the Flowmaster Cat back system. Not only did it pass inspection, it sounds great and seems to have a little more low end power. Installation could not have been easier to my existing shorty headers.

    Yes, I would recommend this item to a friend!

    4 Stars   Sounds great

    This is a great sounding exhaust, but don't buy it thinking it's going to be loud and noticeable, it's still subtle. If you want to have a meaner sounding exhaust, couple this with the BBK off road mid pipe, wether you go long tube or not, losing the cats and updating the pipes will add some volume. Another thing I'll add is that if you know someone who can weld , have them on standby because the ubolts SUCK, your exhaust WILL come loose and twist and start hitting your frame, save yourself the time and frustration and have someone weld the pipes to the mufflers.

    I have had this exhaust before. Exactly what I remember it to be. Great fit and the loud raspy grumble is amazing. All the snaps and crackles on the deceleration is what a fox body should sound like. Mellow while cruising and wakes you up when your foots in it. I recommend this over all others.

    Had to make multiple mods to the pipes for them to somewhat fit. They hit the floor and rear braces. Do yourself a huge favor and buy something better. Trust me move on from this kit.
