Message	I'm in the process of getting my GT28r setup running...I have a 2.5 inch exhaust setup, but I need to buy some new 5 bolt downpipes. If I run the 3" downpipes with the 2.5 in. exhaust system, will there be a worthwhile gain in power/spool? To be honest, I wouldn't be interested in obtaining 3" midpipes and catback for a while, as my car is in need of other things, but while I have the motor out.... I have stock manifolds, dual pop, 555cc injectors, jwt ecu w/s-afc as other relevant mods
