After my JBA longtubes/h-pipe were installed, the car drove like a different car (and obviously, SOUNDED like a different car). While a flat spot emerged at the 3/4 shift, the powerband had noticably changed. I took it out to the track and knocked two tenths off my best.
Prior to the longtubes, I was running 323hp/309 torque--the last mod prior to that dyno tune was a set of Comp Stage III cams. Prior to the cams I ran 300hp, 319trq. Gained hp, lost torque.
After the longtubes, it went in for another dyno tune and my tuner adjusted several things including the cam profile/timing. I jumped to 348hp, 332trq. The car is a beast, and the Goodyear Eagle F1 GS-D3s are completely useless. I had to stick my Mickey Thompsons on it so wouldn't break loose the first two gears.
Here's the dyno sheet:

You have sound clips of your car now? Also, did you have to change out the springs or anything else when the cams where installed?

The stage III Comp cams required new springs and retainers, and (I'm trying to recall) new cam phaser bolts I think.
