Installed this on my '15 Challenger SXT and the improvement on the sound is unbelievable when you accelerate. Of course, if it's noise coming out the back you're looking for then this isn't what you're needing. This only slightly improves the exhaust note, but gives the engine itself a throaty, almost V8, roar when you reach around 5k RPMs. The gas economy went up about 3mpg as well which I won't complain about. Would definitely buy again.
