I've been running a glass pack for the last couple of years and like the sound. Again, not quite the low rumble, but great for clearance and good price.

I have been running 1310 ujoints with 37's and have never broken a drive shaft joint. I have still have CV's F/R and but upgraded the drive shafts. I am pretty heavy on the gas as well.

We've been running one on my friends rig for about 9 months now and it's been working great. We've used it around 15-20 times, on other people of course, and have had no problems.
