Even better sounding then I expected. I have never heard a better sounding exhaust on a mustang, sounds just like the early 90's GT's. I like that the tips are welded to the pipes so there is no rattling around and everything fits nice and snug. Looks and sounds great, bolted up real nice to the BBK o/r pipe. I would highly recommend this combo (o/r x-pipe & Flowmaster 40 series) to anyone looking for that great unmistakeable Flowmaster sound!

I Have been using Flowmasters for over 20 years now and as always this application exceeded my expectations again. There are many exhausts out on the market to choose from but there is nothing quite like the sound that you get from a Flowmaster. From stock to highly modified engines they give me a more modified nicer sound, instead of just a muffled one. The fit was perfect and everything went on without any event. The welds were exceptional and much nicer than I could ever do by hand. I highly recommend Flowmaster to anyone looking for a quality performance exhaust.

Wow ! What a differance ! Love it, was so easy to install... I had gone to my local parts store "A" they sent me home with a trunck full of parts, none of which fit...I took it all back after hours of work. Ordered this system from ya'll, it arrived in less than 48 hours, and took less than an hour to completly install by my self... AND IT SOUNDS GREAT, Thank You

American Thunder Super 40's are the way to go & it was everything I was hoping for. Me and a friend installed it just under 2 hours. The sound that I'm getting from it is that patented Mustang deep throaty sound that's turning heads. The delivery service was very fast to say the least. It was sitting on my porch days before it was suppose to be there. Thanks AutoAnything!!!

The install wasn't too bad my old exhaust didn't want to come off so we had to cut it out which took some time. Everything fits and sounds great.

best cat-back system by far
