The sound was a bit smoother, but overall quieter. Not exactly my cup of tea. However, I thought the car felt a bit quicker in the lower rpm's, which I was not expecting. It feel like it had more low end torque.
Now here's the kicker. I used the Dynolicious app on my Iphone to measure some 0-60 times. The best time I can get now is 5-5.1 seconds with it being about 90 degrees today. In March I was getting consistent 4.4-4.5's with it being 65-80 degrees.
At first I figured it would be the temperature, but I didn't think you could lose .5 second or more. Could the x-pipe be the culprit?
Here is the data from the app for the heck of it:
March, Today
0-10 .78 .89
0-20 1.56 1.69
0-30 2.18 2.38
0-40 2.85 3.15
0-50 3.67 4.06
0-60 4.57 5.07

Are you running the car in C mode?
In order to really compare the two number sets you need temp range within 1-2 degrees.
Was the March run 65 or 80 or 70?? Was the July run 90 or 99 or 95?
If it was 65 in March and 90 in July this will cause a huge performance drop. If it was a 5 degree difference than something is wrong with your car.
