My Commander sounds great under acceleration with this installed. I really didn't know what to expect, but I'm pleased. It doesn't sound any different at idle or mild acceleration but step on the gas and for the first time I know I got a Hemi in there! I haven't seen any difference in gas mileage, actually it might have gone down a little, but that might be me stepping on it to enjoy the growl.
