Installation of the exhaust on my 2013 Silverado 5.3 could not have been easier. Like many of the other reviews, the hardest part was removing the stock system. After that was out of the way, the install was completed in less than 30 minutes. The tone is deep yet not obnoxious, and there is hardly any increase in cabin noise when cruising. After the install, I did a short drive to ensure that none of the fittings would loosen. The next day I drove from NC to MD with no issues at all. Great quality completely satisfied.

Just perfect for me. The exhaust is hardly louder than stock at idle and normal running but when on-ramping and passing it lets out a nice full flow roar and all through the rpm range you can feel how the engine breaths so much better. I like

I orderd my new Gibson Exhaust on monday and got it that wednesday at 400pm and by 530pm the I had the system instaled and took it for a spin. It was easy to put in and has given a noticable power up without all the undesirable racket that you would get with a lower quality product.
