        Flowmaster American Thunder Cat-Back Exhaust

        After looking online and various Youtube videos at what exhaust system would be best for my 2015 RT Plus Challenger I went with the Flowmaster American Thunder Cat-Back Exhaust system and I couldn't be happier with the sound of this exhaust system over the weak stock system. Overall not too loud but has a deep throaty note with very little drone. Exactly what I was hoping for. The price was very good here at American Muscle and the install was very easy as well.
