I am not sure. there was a thread in the GT500 section and a gentlemen said it does work, he called american racing and they told him it will fit. But I personally don't know.
American racing said the headers would fit but the x pipe would not fit a 2012. I am having a set of headers installed today that came off a 2010. I'll let you guys know if there were any problems. Jason
I am interested in just the headers if he takes the X for the right price. I assume I will need hardware, gaskets and O2 leads for the headers correct?
