I recently had the AWE Gen2 exhaust installed on mine. It only has 200 or so miles on it since install and sounds great. Very throaty on start up and a real snarl on acceleration. No drone or resonance in the cabin in any gear at any speed. Perfect fit with no adjustments needed and the Black Diamond tips are just AWEsome. Performance gain is noticeable. Unit weighed about the same as stock. Once I figure how to post videos I will post a clip of the sound. Bottom line is try and hear them for yourself, and find the one that checks all your boxes after all you have to live with it
