Flowmaster American Thunder Exhaust System

Nice system, sound is very nice without being overpowering! Easy install, only issue I had with it was the bolts for the chrome tips either were to soft or needed washers! I broke one of them before it snugged on tail pipe. I got the hardest SS bolts,nuts,& washers from the local ACE store & that worked out well! Would have been 5 star if not for that issue.

System fit well but for the cost it should of included a new clamp for the ball fitting and the clamps on the tips are a joke no way they would hold the tips in place I had to go get new clamps for them for the price you would expect better quality than spot welded tin clamps that brake off with very little pressure.

Very easy to install, form and fit to my g-body car was spot on. Highly recommend, sounds great.

It was a great product, easy to install, and looks great on my truck.

Better quality than I thought it was going to be. Took longer to install than it should have (broken nuts at cat) rest was pretty good! Tip bolt snapped when tightening! Quieter than last exhaust but a nice low growl.

Sounds great, had garage install it. It says it's stainless steel but does not look like it. Clamps not the best, put a tack weld on each.

System was pretty well built. Sound is the deep- throaty rumble but not too loud. One piece wasn't wedged so we had to cut and weld. The clamps are nice BUT they couldn't tighten enough to lock the pipe in place so I had to tack weld pieces. Would still buy, but keep the above information in mind.

Package arrived right on time and looked well packed, fit my truck. Sounds mean! Only problem was I needed a couple of hangers that broke of my truck, could have thrown those in, guess that was my fault. Nothing a weld can't fix.

I was searching for the perfect exhaust for a few weeks and found the American Thunder Cat Back to be the cheapest, yet best reviewed product I could find online. After installing it I found that my power gains and sound was GREATLY improved. I drive a 2007 Chevy Silverado 5.3L V8, and the exhaust really woke up the engine coupled with a Spectre cold air intake I bought as well. The cat back is NOT LOUD so if you're looking for a crazy throaty sound this isn't for you, but putting your engine above 2000 RPM's does make a pretty mean sound. This being said it is the perfect modification to make me and the girlfriend happy, and we can still keep a conversation in the cabin, unlike when I had a monster of an exhaust and you could barely hear the radio. Overall rating is 10/10 if this meets all the specific requirements you are looking for.

Haven't installed, lots of work left for installation of exhaust system, car is being worked from ground up, had mustang 49 years, bought ne ! I can say that everything looked great and had done some homework on this exhaust and liked what i have seen! Shipping was fast, just as good as any price on this system I have seen, happy for now! Had to pick how long it took to install and performance rating to submit my review, need to change that!
