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.

Wih the 3.7l at 210 HP, there isn't much more power to gain, as far as HP is concerned. The vehicle is just too heavy. I love the look and the sound is great. Have not noticed any improvement in gas milage either. I got a good deal on it and always wanted the 77, so i'm happy with it.
