Prchased the SS version for my 2007 F150. Overall very pleased with the quality, fit & sound. Could not give 5 stars because the SS clamps just do not tighten enough. Have read about this issue on the forums

American Looks and Sounds Great

Bought this kit off AutoAnything. Once arrived had a local shop weld it on for $60. Looks and sounds great, definitely got that old school rumble. Not to loud, can still enjoy music without the exhaust droning it out.

The tail pipes are very quality made the stainless is very smooth no burrs or misfiring pieces and it sounds great. Only had a small issue getting the rear exit pipes to line up especially on the left side but nothing too too bad. Only slightly disappointed in the small 3/8 bolt and but they give you for the chrome tips they almost don't have enough strength to clamp with out bending or stripping out. I just put some 1/2 inch stainless shank bolts in them no biggie. Enjoy the sound..recommended!

Sounds great! F150 5.4L

Upgraded from a single outlet Super 40 muffler and I can tell you the dual system sounds much better. It's not overbearingly loud but still has a great rumble. MPG gains are very slight but throttle response is definitely improved. I would recommend getting 3.5 or 4 inch tips though...the 3x12 ones included with this system are a little small at least for my taste.

Well satisfied.

After several weeks of research and reading reviews and watching videos I feel I made the best choice for what I wanted , my American thunder delivers the sound and added throttle responds as promised

Great Product for the price.

Very easy to install. Great look. Better gas mileage. Much better than stock system. Didn't increase any horsepower in my case. Sounds pretty good but the drone sounds keep it from getting a perfect score.

Recommended with gotts mod(look it up)

This is an awesome exhaust system! I have a 05 f150. When I drive and have my windows rolled up; I can still hear it, but it's not annoying loud because it's a low-pitched noise. Not like a rice burner or anything. For me, it's at it's loudest right around 2000rpm but still able to hear it low and higher than 2000rpm . I love the sound of it, I think it's great! Especially when started from a cold start. It was fairly easy to intall, had to modify and cut pipe a little and tack weld.

Flowmaster Exhaust, great quality, great sound, great price!

Flowmaster provides complete, easy to follow instructions. Flowmaster uses a heavy-duty, stainless steel pipe, that's 3-inches in diameter. Flowmaster provides you with a lifetime warranty on this exhaust. The pipe is mandrel-bent, meaning the bends are full-diameter, which allows for full flow! What good is a 3-inch pipe, when the bends are only 2-1/2-inches in diameter? This is the last exhaust you'll buy, as long as you own your truck!
