WTS 2011+ MRT Interceptor Exhaust

[Swiesz]

Hello, like the title states, for sale two month old MRT Interceptor axle back exhaust for sale. Pics below. Nothing wrong with the exhaust, just want to go to the 2013 GT500 quad exhaust, would be willing to trade for that setup. Only 600 miles on exhaust. Paid $600 new, looking for $450 shipped or OBO. PM if interseted. Located in Detroit
