It is awsome,took less then an hour to install on my truck. Every thing needed was in the box.

I had the Flowmaster American Thunder Series on a 2001 Yukon Denali and loved the sound. That option was not available for this vehicle. I spoke to the Flowmaster rep and he recommended the Force II as a good option. I did not want a loud system but wanted to get a good low rumble. The sound is exactly what I wanted. At takeoff you hear a good low rumble but at cruising speed it is barely noticeable in the cab. Basically no drone present. I do get some burble when the vehicle is in the V4 mode.

Just what I wanted. The tone is deep, but unintrusive. Love how it sounds. Installation was easy, installed in my garage, on the floor. It took longer to get the old one off than install the new one. My collar clamp on the old exhaust broke off on removal, you may want to get one from GM to have on hand in case that happens, plus if your working on the floor, no lift, you'll need to jack up the bed of the truck to increase the gap between the axle and bed to get the old exhaust out over the axle
