Flowmaster makes a quality product, fairly easy to install. They look better than the stock mufflers and sound great at idle and under hard acceleration. But at steady lower rpm's they have an annoying droning sound.Flowmaster 817496 American Thunder Aggressive Sound Dual Rear Exit 409S Axle-back System

Bought this set of for my 2012 Mustang GT.Very easy to install, should not take more than an hour and a half to get done with maybe a couple ramps on the back of the car.*** Who should get this exhaust? ***Those that like the attention of everyone around them, regardless of what it sounds like inside the car. These will have every single person you drive by turning their heads. It's indeed that classic monster 5.0 exhaust note you are looking for.*** Who should not get this exhaust? ***Anyone that has any concerns of harmonic resonance in the car, or "drone". These mufflers drone pretty bad between 1500 and 2500 rpm. This issue can be dealt with in a manual by just switching gears. In an automatic, you're kind of stuck with it.The exhaust sounds great, on the outside. The drone was just a bit much for me, and I ended up swapping them out.

I listened to 100+ sound clips and read a bunch of reviews. This is by far the best sounding exhaust on this car. Very deep and aggressive when giving gas but not so loud when cruising. There is no drone and that may be due to a redesign in 2013 or road noise elimination. I love it when I cruise through a parking garage or under an overpass. It sounds like a beast and any sound clips don't give it justice. This is what the mustang should sound like.The price with amazon was the best and shipping/packaging was superior.
