Probably has straight cut gears. I could be wrong, but it sounds awesome either way.

Normal gear boxes are helical, which means they are diagonal and they 'mesh' together in turn. Straight cut gears are parallel and come together at a 90 degree angle. The consensus is straight cuts are significantly stronger and can take the abuse. The major downside is the increased noise.
Hope that helps. I'll try to find some pics because that may be hard to picture.
EDIT: Perfect example:
Ah yes, very helpful. I always figured it was diff or tranny noise.

The car is a GT3 Cup Car.
Here is a pic of it. Steve is right about the noise.
I seriously need to get an external Mic.
Cool vid.
