I have a set of 2012 GT500 mufflers that have been retrofitted for an 05-09 GT or GT500. They are in great shape, no rattles, dents, etc. I would like to get 275 shipped for these. These sound awesome with an offroad set up. I have run them with longtubes and an offroad X.....pure awesomeness. If the price is too steep, make me an offer.
