but i like it for the most part. it has a horrible drone in sixth gear at 1500 rpm. 2000 rpm cruising at highway speed is ok. it idles quietly and when i punch it it's not all that loud. i like the way it purrs when i'm revving through the gears and it cackles when i shift. nice boost in power as well. no it lights up the tires when i punch it in second. all in all great fun

I bought the updated model (introduced 8/15) which instead of being an S type muffler the new one is more of a turbo type and it is very loud especially at start up. Once on the road though the sound is not overbearing but when you get your foot into it...well I did say it was loud.

Started with Pypes Pype-Bomb Axle-Back exhaust (muffler delete) on the wife's 2015 Mustang GT-automatic. Sounded great to me- with little or no drone- but waaaaay to much volume for her. Went with the Flowmaster American Thunder Axle-Back and found the perfect balance between stock and muffler delete. Just the right tone, muscle-car sound at acceleration, quiet at cruising speed. Had local auto repair shop install, took less than 1 hour. Delivery was prompt, package well secured, fitment good.
