At an idle I really couldn't hear a difference untill I reaved my engine to about 3k rpm. The overall horsepower gain isn't alot but I could tell im getting a quicker acceleration closer to my top end. And in about 3rd and 4th gear my engine has a deeper sound higher in the rpms. Overall i'm very happy with my purchase and can't wait to hook up an exhaust and see how much of a difference that makes.
