    I have this on 2016 GT and it sounds alright down low, but higher rpm doesn't sound that great. (in my opinion) If you have the windows up on the highway at 2k it will make your ears bleed. They're much better options in my opinion.

    I compared a lot of cat-backs and listened to everyone of them. Videos don't do any of them justice. But hearing this one in person, it's exactly the sound I wanted from a cat-back. I love how it echoes off walls and screams all the way to redline. It does resonate a bit a highway speeds with the 3.73's, but speed up a little more and its relatively quiet. Considering there's no actual muffler, it's a nice balance between "I can't hear it because the stock mufflers" and "Put the cats back on, it's too loud." It is the loudest I've heard with cats, but I've driven with them since April, and none of my neighbors have complained. And I work all times of day and night. I've always taken the cats off my mustangs, but this will be the first time that I will not have to for the sound I want. If you want it loud, this is what you want. Some of the best quality I've seen as well. Top notch product.

    This exhaust puts all others to shame. My dad helped me put it on in the driveway. We used ramps and jack stands. The first time you rev it up you know you made the best possible choice. OUTLAW BABY!
