No that little reduction really does not do much 3" moves plenty of exhaust...just remember it used to be full 2.5 inch so that little bit doesn't do any damage your probably talking not even one horsepower if any??
Does the stage 2 AP give better fuel mileage too...considering it leans out the very rich running stock ECU and your not driving like you stole it?? I would think that it would does anyone know ??
