BabyBenz, yes it definitely did sound nice, just a bit still was a bit too loud for my local in-town driving. Although I had it on for about 20 minutes I did not take it out on the highway for any speeds over 50. I did notice, or felt I noticed, the better off the line performance plus I also like what another poster had listed as a plus; being able to actually hear the up-shifts.
Shoot me an personal message if you need more info and I will be glad to respond.
