Always love Flowmasters and have had them on our family's trucks for years. Flowmaster sales and customer support folks are absolutely the best! Really nice system and pretty dang easy to install with simple tools. Make sure you have a breaker back and a deep 15mm socket for the install. Feedback: The exhaust tips wouldn't tighten enough, so have to tack them probably. Clamps have to be adjusted to the right position or you have small exhaust leaks which is slightly tedious.

This exhaust sounds great, the cost with promotions was phenomenal, the shipping was fast, installation did not take long, and overall the experience shopping with AutoAnything.com could not have been easier. BUT for whatever reason the hangers on the exhaust did not line up and so I had to modify a bit to make it work. I even welded the extensions that came with the system onto the muffler end that plugs into the cats, in order to gain a little length. Overall great purchase!

I installed the flowmaster American thunder exhaust on my 2017 Silverado all went well, my truck sounds great and i did notice an increase in my gas mileage. The exhaust was easy to install, I opted for the side exit rather than the rear exit.

Sounds great and install was simple. Surface rust already showing in the box. A bit disappointing on a $500 axle back system.
