I ordered the 50 series HD Flowmaster muffler 3.5" in/out offset for my 2011 GMC CC 4x4 6.2L hoping to get the familiar sound and performance flowmasters are known for. I did notice some extra grunt, but disappointed in the sound. Although I did not want it to be loud and obnoxious, it is quieter than I expected, though it does have a decent rumble at idle over stock muffler, and does sound better when accellerating. Overall the installation was a breeze, muffler shop only charged me $20 bucks, it does sound better than stock, and I have noticed a little better performance and throttle response. I am pleased overall with my purchase experience at Auto Anything, reasonable prices, and the free shipping is a big plus. I will be a return customer for any future purchases.
