Oh yeah, pretty big difference at WOT. It is loud enough for me now, actually SOUNDS like a V-8 now! Like you said, I don't want it to sound loud and obnoxious like some trucks/mustangs/TA's you see. I'd rather take the money I'd put into Flows and look into some kind of cold air intake system (if they make them).
