This is a 2012 Dodge Challenger SXT-Plus (3.6L V6) with a Flowmaster Force II exhaust kit. It's a cat-back system with 50 series delta flow mufflers. It's probably also worth mentioning that there is a Mopar cold air intake installed which alters the tone slightly. Hopefully this gives you an idea of how it sounds inside and outside the cabin.
