i would imagine, alot more....but.... the v3si really is silent. it does make a lovely low speed whistle though, you can hear a muted blowoff sound at higher revs, so im thinking you with your stock exhaust should be getting some nice noises from up front, i would definatly advise an exhaust upgrade!! you'll definatly make more power now your f/i. remember your squeezing in much more air, you need to get it out faster ;-)
