System was fairly easy to install, the only problem I had was a missing hangar on the truck, other than that installation went well. It has a nice mellow tone at idle, and sounds great when you get on it. Not enough to upset the folks on the street where I live. It should last for years, pipes and muffler are heavy gauge metal and aluminized. I am very satisfied with the system.
