Beast Mode!

I had these installed on my 2016 Challenger RT and they sound incredible! These things growl on ignition and roar when you accelerate. The only reason I didn't give 5 stars is because of the loud droning sound at certain rpms. It isn't unbearable but it is extremely loud inside. I however think the overall monster sound is worth a bit of drone.

Can you hear me roar?

I'm very impressed with this American Thunder system. I listened to a lot of exhaust systems online and how can you go wrong with a proven system like Flowmaster American Thunder? I did the install completely alone but of course it would have been easier with another helper. I took my time and made sure everything fit right and was positioned right and the way I wanted it before tightening every clamp down. Took my time over the course of an afternoon and when I fired her up....WOW!! Love it!

This exhaust deletes the res. and ups the growl! Stock exhaust is nice on the r/t but this American thunder makes that hemi purr like a hellcat. It takes some adjustments to line up perfectly, but anyone with a torque wrench will have a great time installing. Great buy!!

Good Value

Installation was fairly simple and quick. Sound is incredible and throaty. Performance increase was barely noticeable. All in all I am very happy with the exhaust.

Looking for a little more sound for my car, Flowmaster provided that, system has increased the rumble level. As stated in their ad system does produce some interior noise, still evaluating, but may have to buy some resonators to reduce interior drone. Overall satisfied.

My 2015 Challenger R/T had the look I wanted but the factory exhaust was too tame. The Flowmaster American Thunder gave my car the growl to go with it's look. Love my car and the sound turns heads.
