  Awesome!!!!

  I just installed this system on my '86 GT convertible. It is the perfect sound! Loud but not obnoxiously loud. It only took a few minutes to install at my local shop and they look great too. Shipping was very quick to Connecticut (next day) for no extra charge. Buy these pipes!

  Awesome!!!!

  Gives the true 90's mustang sound. I would have given it 5 stars but if your running anything over a 275 rear tire everything gets real cramped but other wise very happy with the polished tips. I would also get this system welded.

  The classic musclecar sound i was missing

  This exhaust came really well packaged nice and shiny took about 30 minutes to install really easy and the sound is amazing my last ones where blown out like a tin can it was time to change them and now its less louder but the sound quality is at its finest. I live in canada and it took a week to get here pretty fast. Only think the passenger side muffler is vibrating against the frame a little self initiative help fixed the problem.

  American thunder car back

  I installed the American thunder 2 1/2 cat back exhaust in about two hours. The product went together great , but had to put a small weld around the tail pipe because of exhaust leak. I wanted the iconic fox body sound and I got it.

  Fit great

  Great sound, easy to install. Only complaint was cheesy exhaust clamps, broke one and smashed my knuckles. One muffler had a slight dent, but I'm not picky.

  Excellent sound

  Fit and finish excellent.Took a little tweaking to line but lined up perfectly. recommend installing band clamps instead of the supplied clamps for a cleaner finish . Along with a set of BBK shorty headers and Mac Pro-Chamber exhaust sounds awesome and not too loud.took about and hour to install.

  Awesome sound!

  This is the reason the mustang has that iconic sound. These are a must have for anyone looking to make their car loud. Great flowmaster quality and fit.

  Flowmaster American thunder

  Great exhaust, purchased this for my 92 lx and American Muscle got it to me in about 2 days. The install was straight forward taking a little over an hour with basic hand tools. The system looks great and sounds even better. I def recommend this system for anybody with a fox mustang looking for some mean grunt.

  Great Catback

  before buying this catback i had stock headers mid pipe and super 44 mufflers with the pretty much stock exhuast i wasnt getting much sound out of my exhaust so i decided to upgrade and bought bbk equal length headers, bbk h pipe with high flow cats match all of that up to this catback man what a world of difference car sounds amazing now.

  great sound

  My 13 year old son and I installed this system on our 1992 Lx Summer edition. We all so used the bbk off road H-pipe . We installed the system in an afternoon,fit well but a hoist would have made it easier. The sound is fantstic,lots of people ask about it.Just need to add the BBK headers to finish it off.

  The Right Stuff

  Everything you need is in the box. Fits with all factory brackets and hangers. Sounds great! I haven't used my radio since the install; I just listen to the car. Good Flowmaster sound w/o being too obnoxious. http://youtu.be/gs4-YuyKXH4 The video doesn't do it justice but take a look anyway.

  Installation on a 93 Cobra

  The product came packaged very well with little chance of damage happening during shipment. I purchased this kit for installation on my 1993 Cobra and although it is not mentioned on the application guide it does fit with a very, very slight adjustment to the tail pipe hanger brackets. The system went in very easy and fit very well. The slight adjustment is done to the tail pipe hanger bracket which allows the tips to clear the rear skirt. I trimmed the tab of the bracket that installs into the frame to allow a very slight pivot down which in turn allowed a slight drop (approx 1/8”). The sound is great, not overwhelming but a very attractive tone and growl when throttled up. I am very happy with the product…

  Sounds Great, But....

  The sound is pretty sweet after a lengthy install on these bad boys. My main problem was the clamps they sent with it. I definitely recommend getting 3/8" clamps to replace the chinsy 1/4" ones they send with the system. Then you can get a good bite down without snapping them from the torque (like I did on one side). The other problem I encountered was the hangers coming off the mufflers and tailpipes don't have a head on them, like my stocker ones did, to keep from slipping off. After a mellow ride I checked them thoroughly for problems. I noticed on one side it slipped off the mounting hanger. To resolve this, I was fortunate to know a welder friend who welded washers to the ends of all the brackets to keep the rubber grommets from slipping off again. After some hit and miss, overall the sound is sweet...especially with the top down! The only other issue I have is why they have the tailpipes going on the inside of the mufflers verses the outer side. But oh well, sounds great and I'm happy. Speedy shipping as always through AM. Good luck and don't forget the 3/8" clamps!

  Great product

  I shopped around for a exhaust system and decided that the flow master system was the best product for the money. With their reputation you cant go wrong.
