If it were me I'd upgrade to 3 inches. 2.5 seems a little small for boosted applications, especially since many of us V6 naturally aspirated guys upgrade to 2.5. Just for your info, the Magna (Diamante) and Galant sold in the Pacific rim use 2.5 from the factory. The U.S. seems to be the only 2.25 inch non-mandrel bent from the factory.
