Hey guys have a set of magnaflow competitions for 2013+ gt500's, they sound freakin sweet. I have roughly 1500 miles on it they're in great condition just a bit dirty. I'm in SoCal but willing to ship, it costs around $50 in the CONUS. looking to get $500 shipped, original MSRP is around 660 i believe. OPEN TO OFFERS. PM me.
