The stock headers and y pipe really attenuate sound. The Flowmaster sounds great! It enhances the nice rumble of the 6.2L. Build quality is excellent, installation was a breeze. I shattered a sawzall blade cutting the enormous stock pipe. Be careful. My blade wasn't long enough to pierce the other wall of the pipe at it's widest point. Instead the blade hit the wall and shattered. I finished cutting the stock pipe with a hacksaw.

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.
