    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.

      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 .

      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! .

      This Cat-back system looks, sounds, and performs great. The sound is not obnoxious at idle or low speeds, but is properly obnoxious when you open it up. The exhaust note is a throaty resonance and the downshift rice crispies snap, crackle, pop....awesome! The only downside is that you will get poor gas mileage because you are going to always be in a lower gear with your now lead foot glued to the floorboard. Cramps in your face from the perma-grin can be a problem, as well. That sound. You will need that sound!! You are slave to that sound!!! Now you need gears, cam, heads, it's all over for you now. Take out a second on the house and tell the kids "it's community college." Thanks AM! Another broken home! :D

      EXCELLENT easy to install. the hardest part was centering the pipes with the cut outs in the fairing. look good sound good and they are stainless so i don't have to mess with another exhaust for a long time

      I laughed out loud

      I guess I didn't know they'd be so quiet or maybe it's just quiet since I've been running one muffler for like 6 months...I can actually hear the radio I was impressed with the ease of installation...great job.

      This is a great exhaust. The sound is perfect in my opinion as I think it has a great sound that is just a bit louder than stock, you hardly notice the increase when cruising but if you get on it it comes alive a bit but won't wake the neighbors or set off alarms. Throaty but mellow until you floor it, just right. American Muscle service couldn't have been better, all items I've ordered got sent out the day I ordered em.

      Sounds great, but we did have to make some modifications. The tips didn't want to stay even, and the hangers needed to be heated and bent to properly hold it, otherwise it was rubbing the tires

      Installed fairly easy, a few minor tweaks needed but nothing special, Nice deep rumble at idle and roars when your on the gas. Best bang for the buck you will get.

      Installed on my '88 GT. Sounds nice. Very little to no drone on the highway (70mph). Getting it in there was a bit of a challenge but dont rush it and you'll be fine.
