I must start by saying I love the flowmaster sound. I installed the American thunder cat back exhaust system on my 2012 Durango R/T and I found the fit to be frustrating to say the least. I had to cut 1/2 an inch off each scavenger pipe so the system would clear the spare tire shroud, and then I had to shorten the hanging brackets on the left muffler so the exhaust tip would fit the exhaust opening correctly and match the right side. Not the easiest install but my Hemi sounds awesome!!!!

Horrible Sound - Not for MDS Hemi

Was a terror to install. Had to modify. Leaked and rattled until all joints were welded. Clamps were worthless. Sound is horrible. Have the 5.7 Hemi that shuts down to 4 cylinder when cruising. Droning was unbearable! Sounded like a Neon gone wrong. Called Flowmaster & they admitted to knowing about this drone. Do not include resinators with system for Durango yet they are on the systems for the 300C and Charger with same motor. Makes no sense! Flowmaster did ship out resinators after multiple calls to them and Auto Anything. Don't buy until they fix this issue unless you like a horrible droning vibration in your ears!

The overall sound is definitely better than stock. I was worried that the interior sound would have to much drone to it like most Flowmaster systems, but at cruising speeds its just noticeable. Didn't really notice any horsepower gains, maybe a little better MPG. The whole removal and installation process took me a little over two hours. In the instructions it says that it's a tight fitting system and they weren't lying. I had to cut off about an 1-1/2" of piping on each side before the scavenger assembly just to get it to fit together.
