I am super happy with this Flowmaster American thunder system! I had a Flowmaster system on my previous truck, and came to love it over the 11 years I owned it. Auto Anything was extremely fast shipping! The removal of the old exhaust and installation of the new Flownaster system literally took less than an hour, sounds amazing, and I couldn't be happier!

This wasn't hard to install if you have some wrench time and sounds mean at start up nice deep tone that's know from flow master have to say was a little louder than I thought it would be but at 55 mph hardly hear it but a little drone noise.

Great sound, a little louder than I expected but overall a great system. Only issue was the hanger/clamp is only 3" ID and when you have to put it on the rear exhaust pipe and muffler outlet, it's nearly impossible to get it locked down with just one person.

I have been adding things to my F150 from AutoAnything, I have Superchip on for over a year , just added the Exhaust system been looking for 3.5" or 4" system got it not only look nice it sounds great and the back pressure from the stock to this open flow my truck rolls better and gets better mileage. If I baby my truck I can get 20.3 miles per gallon before the exhaust exhaust change the best I could get was 17.3. But I like the sound and love getting on it so I'm getting 15.8 which is great.My next purchase will be the K & N cold air box from AutoAnthing prices are the best! I have 20" BF Goodrich/TA tires with nitrogen in them which also help the mileage.
