"Great sound, was a little more than I wanted to spend, waited until I got a coupon to purchase. Would have been really easy to install if truck was on a lift. Having install it on the ground was a little more difficult. Still a great system" —Craig D from Kansas City, MO bought a Flowmaster Exhaust Systems for a 2012 GMC Sierra.
