Nice rides! My 1500HD (6.0L/4L80-E/4.10) needed the Black Bear tune and Magnaflow exhaust to wake up, and then it was awesome. But as @devildodge knows, my stump-pulling '01 2500HD with the 8.1L/Allison/4.10 combo (and dual chambered exhaust) was a BEAST. I still miss the earth-shaking rumble and Allison pump whine of that rig.
My 1500HD only had 3.73's but my 8.1 Suburban had 4.10's. The 8.1 is for sure a beast and sounded awesome with the muffler I had on it. I honestly would still have it if it didn't start nickel and diming me so bad. It was also starting to show some rust on the rockers.
