Yes on the XREAS. I have a 2004 Sport Edition to be exact. XREAS will have no effect with the Magnaflow system. The XREAS becomes tricky only on the borla/trd exhaust systems because they have a "dual" exhaust exit. To get that exhaust to exit on the driver's side rear, they have to go around the spare tire. Since the magnaflow only exits behind the passenger rear tire, no worries.
