Since you're looking at just a slip-on, and the exhaust headers through the collector remain stock, you should be able to make it work. The Coffman replaces the undertail on the '09 with a shorty on the collector, just as it goes on the collector of the '02. The possible differences would be mounting points, the angle off of the collector and diameter of the slip-on where it meets the collector. These are not insurmountable problems but, worst case, may require the fabrication of a short section to bridge between the collector and the slip-on, which a good muffler shop should be able to do. Best case, it slips on and off you go. Good luck.
Do you have to leave so soon? I was just about to poison the tea.
