"Self-installed this system in my F150. About 3 hours total, with most of that getting the old pipes/muffler removed. Fit was perfect, just took a few minutes to get everything aligned. One note, the cat extension pipe to the muffler does not have a hanger like the stock pipe. Hope that never becomes a problem, but the system seems pretty solid. Sounds authoritative, but not loud or obnoxious. Added system to aid in towing, but haven't tested it yet." —Michael S K from Laughlintown, PA bought a Magnaflow Exhaust Systems for a 2011 GMC Sierra.
