So to sum it all up. 2.5 liter with headers, high flow cats and factory S muffler with crios mod. What do you think? Any worthwhile performance gains to be had? I'm sure it would sound different, maybe better.[/QUOTE]



You will lose low RPM torque which I assume is the worst thing about a 2.5L, having never driven one. If I were you I would replace the rear pipes & think about removing the manifolds to "port & polish" them before reinstalling.
