Used, but in great shape. GM 19303337. It's for a 5.3, crew cab short bed/double cab standard bed. It comes with a pair of chrome Gibson tips, but I have some optional black chrome Borla tips. There is a small dent on the muffler, but that doesn't affect anything. I'm asking 650 for the system with the chrome tips. Black chrome tips are used for a couple hundred miles, but just barely. They are still in great shape. $100 for the Borla tips. GM has the exhaust from $1,000-$1,200 and the black chrome tips are almost $200. 650 system 700 system with black chrome tips too (4 tips total) 100 for the black chrome tips separately. I'll have to get it boxed up for some exact dimensions for shipping costs.
