        4 1987 GT - Vulpes Installation Time: Afternoon

        LOUD racecar sound

        I was wondering just how loud it would be, and I was absolutely shaken by this mod. I had an open x-pipe before and that was nice, but this really set things apart. it has the high end growl that you would normally see on newer mustangs. Absolutely a good choice, although it's genuinely so loud you may get complaints or it might sacrifice daily driveability. frankly, i don't care, i love the sound. I have mine combined with BBK shorty headers and a BBK x-pipe. Only complaint is the rear tips are unfinished steel, but otherwise perfect with fitment and everything.

        Cat back exhaust

        Excellent system comes with everything you need. I just had to do a minor modification to fix on the drivers side. Definitely would buy them again.

        4 1990 GT - TimT Installation Time: Afternoon

        Good for the price

        Put this system on, along with a MAC h-pipe. Great tone under acceleration, and zero annoying interior resonation. The fit was decent, and only required a little fine tuning. My only minor gripe is that the tone just off idle could be better. Good bang for the buck.

        The pipes really Accentuate the power of the 5.0. A little loud at first but they really grow on you .

        4 1989 GT - CharlesJW Installation Time: Afternoon

        Very good exhaust for the money.

        I purchased this cat back to replace a flowmaster set up that had rusted away. I was able to install it in my driveway by using two jacks and doing one side at a time. The only complaint I have is that in my humble opinion the flowmasters sounded better. For the cost, you can't beat this exhaust. Its not obnoxiously loud, but still throaty and aggressive.

        decent deal- too loud

        decent fit and finish at a great price but obnoxiously loud on a mild street car- maybe if it made more power it would sound better= bought another brand of muffler to substitute

        Great improvement

        Easy to replace and sounded great. For normal driving sounds just a little better than stock, but really changes when you punch it.

        Fits Like A Factory Exuast

        Very happy with the whole system. It came in 2 days. All parts were included and went together easily. Directions were good and with minor tweaking and patience the mufflers & tailpipes location were dead on to the Factory originals. Had to call Pypes for muffler In/Out direction; But they helped promptly. Went right through Jersey inspection 1 week after install. Sounds great! .

      2 Top Rated Questions

      I had a shop order and put this on my 88 GT said SS but a magnet sticks to it is there 2 different versions of this exhaust?

      Why won't these work on an earlier foxbody? I have an 84 convertible that I would like a full exhaust on but I'm not finding anything that will work with it? Do you know the reason?

      • This is designed for the 87-93 Mustang models. Unfortunately the fitment for the 1984 models is different and therefore this exhaust will not fit.
