The exhaust sounds great for my 2017 Sierra. Not too loud and cab noise only gets loud while cruising at 75+ but it's not overbearing. The installation wasn't too bad after I got a cheater bar to tighten the clamps. I also added a tuner super chip which is a must if you want to feel the true power your truck is capable of.

Exhaust system sounds great and was easy to install. I was disappointed with the clamps that came with it since they did not tighten down enough to hold the pipes in place. For a $750 system everything included should work as intended. I had to go to the auto parts store and purchase 5 cheap clamps as replacements. Other than that I would recommend the system.

The system fit great, and the sound is exactly what I was looking for. It took me around an hour and a half to remove the stock system and put this on. The sound is a loud deep rumble, without being obnoxious. The only thing negative is it doesn't sound very good in v4 mode.

Good system, sounds great. Install wasn't too bad, definitely need two people. The bolt in one of the clamps was cross threaded and set the install back a bit. The big disappointment came when bolting on the tips. The bolts in the kit are CHEAP! The nuts stripped right off the threads when I tried to tighten them down. Had to go to Home Depot to buy quality stainless steel bolts.
