Best Option for Factory Single to Dual Exhaust

Easy installation with clearly labeled parts for the shadetree enthusiast, and excellent fitment and build quality. As others had mentioned there is a drone between 1400 and 1900 RPM but its not too bad; doesn't vibrate the cab as a flow through race muffler would. Great sound at idle and above 3000 RPM is when you really hear the sound. Installed on 2016 Power Wagon.

Just installed an American Thunder system on my 2017 Ram Powerwagon. Great sound. This is the fourth exhaust system that I purchased from you and they are all total quality. Thanks! Bear

Sounds great.

Overall the exhaust was easy to install on my 2015 Ram 2500. The only problem I had was with the hangers welded on the new exhaust. I have a feeling that they are going to slip out of the stock rubber hangers on the truck because they are not flared at the end like the original exhaust. They are already starting to pull out a little bit as I drive and it settles. The truck sounds amazing though and I can feel a slight increase in power and mpg.

I ordered this for my 2016 power wagon and was told it wouldn't fit, with a few minor modifications it is all installed on my truck. Looks and sounds great!

I really like the system for my Truck. But would like it even better if I got all the parts the first time around. Still waiting on two missing parts.

this kit is better than i thought it was going to be. i really like the 3" pipes. at first i didnt know if it was going to be loud enogh for me. but after installing which took no time, i realized it was just right for me. it was plenty loud inside and outside. loud the sound. at idle has a mild roar but when you step on the pedal it really sounds loudddd. and it reallly helps with gas. use it to tow some trailers and what a difference. just make sure you put the k&n filter to help
