Those sounds are nothing special, any synth can make them, start with a saw wave form on 2 osc, detune the 2nd one a lil bit, add a bit of noise. That should get you started somewhere in the neighborhood. Try scrollin thru presets that you already have and look for something close to that and tweek from there. Also, since that rule song starts with just those synths, you can sample them and tweek those. Million ways to skin a cat. Hope that helps.

Forgot to add, i love hard saw synths, for me, lil jon's earlier work really used to make my face scrunch up. Check his synth work on "put ur hood up". I love that hard edgy sound. Especially when its loud *scrunches up face and bobs head*
