I purchased this cat back system for a 2013 Dodge Challenger RT. The mechanic had no issues installing this system and everything went smoothly. The system reuses the OEM exhaust tips and keeps a nice stock appearance. I haven't driven the car enough yet but can say that there is definetly noticeable interior resonance right around 2000 rpm just like Flowmaster states. At other rpms the system has a nice deep rumble and cruising in overdrive at steady speed it's almost as quiet as stock.

I recently bought Flowmaster's Cat-Back American Thunder for my 2015 Dodge Charger R/T. It certainly gives the car a more aggressive sound and more muscle car experience, than the stock exhaust. Installation was was a breeze when I used a car lift and power tools, about 2 hours. Removing the stock exhaust was the most difficult part of the process. I highly recommend the American Thunder as it will certainly get those heads turning!

Stainless Steel exhaust is nice.. But it is thin walled and yet well made.. a few mods and it`s on there.. Too early to tell if it helps MPG or not.. We will see how durable it is in the long term.. Overpriced !

Purchased the American thunder for my Ford F-150 and love the sound. Haven't been able to keep my foot off of it enough to see if there is an increase in mpg . Have felt a difference in throttle response when towing especially. Not too loud in cab but enough, wouldn't want anything louder.

This system is pretty simple - no resonators means the growl comes into the car a bit more, but that's exactly what I wanted as I tried Corsa and have heard the Force II and it was a bit mellow sounding for my taste. If you want a good rumble when you step on the gas but still be able to live in the car while every-day driving, it works great! 2015 Charger so stock appearance remains, which is what I wanted, but some may want the look of new tips....
