Sounds nice..

Reviewed By Justin N (PLEASANT PLAINS, IL) Reviewed for a 2016 Chevy Silverado —7/20/2017 8:07 PM

Was an easy install. It fits great. It sounds nice, a rumble sound. It's not as loud as I want, so ill probably delete the resonator and itll be much louder. Would recomend.

Great Product

Reviewed By Kevin P (TERREBONNE, OR) Reviewed for a 2012 Nissan Frontier —7/20/2017 1:15 PM

This was the deep sound I was looking for. Definitely turns heads but doesn't annoy you on the highways. I get that rumble when I reached highway speeds and no drone. I'm very happy with my muffler. The wife likes it too, so that's a bonus.
