I can't believe I haven't seen anyone else think about this.
Listen to it. It's cheesy as heck, but from a technical standpoint, it's decent. The people who made it clearly had made something like it before.
Which means that it was recorded, somewhere, by an actual rapper, or rap group. Which means that, somewhere, the artists that made it have an actual discography.
Somewhere, there is an artist recording music in the style of the Piraka rap as a career.
It's been 10 years, why has no one tried to figure out who this was?
