  Lost power

  I wanted my stang to be louder so I purchased this exhaust system. I didn't need at as mine was already a flowmaster system and was in great shape, I think a sale on the American Thunder made me do it. Anyway, I truly believe I have lost some power, exhaust is loud, at certain steady speeds it resonates inside the car and you either have to speed up or slow down to get rid of that. They are fine but I should have stayed with my other exhaust.

  4 Star kit with 5 Star sound!

  Pros: 1. If you want that amazing "Flowmaster" exhaust note then you have found it. The Super 44's blow away the 40 Series in my opinion. They are a good bit louder but the tone is amazing throughout the entire RPM band. 2. The chrome finish on the tails is extremely nice. Cons: 1. Be prepared to make a trip to the muffler shop. The mufflers need to be opened up on the tail pipe ends so the tails will slip inside of them. Errr! 2. Don't even think about using the wimpy 1/4" clamps that come with the kit. Go to the parts store and pick up some 3/8" clamps for a few bucks. The 1/4"ers will snap easily.

  The Real Deal

  I wanted to make my 1986 5.0 GT look right, sound right, and feel right. This product gave me everything I wanted. When a Fox body Mustang looks right with the polished underhung exhaust tips, sounds just right with the unmistakable ear pleasing Flowmaster Mustang growl, then it magically feels better all over - and so do I! Thanks American Muscle!

  Amazing sound!

  Paired with the Mac Off-road H pipe sounds amazing! True Foxbody sound that we all have come to love! This exhaust is a great set up and fits nicely but you do have to take your time and put it all in and together and make sure clearance is good before tightening anything! My only complaint is my drivers side tip sticks out a half inch further than right side so will have to take to exhaust shop and have them cut 3/8 to 1/2 inch off the part that goes into muffler to get it to match! Takes a full day to install it and H pipe and you will need to either have a lift or jack that will raise it high enough to route tail pipe over axle, I had to take it to mexhanic with lift to get them to install tail pipes due to this issue.

  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.

  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 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.

  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.

  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…
