Really worth going with the 3" catted H for factory connections over the MRT catted H pipe for a 2008 GT500?
Only have a 2.5" pulley, CAI and tune with a cut and clamp ProChamber...can't imagine the difference of 3" piping would be too noticeable, especially since the manifold and catback connections are still 2.5".
