Idling+backfiring

Why is it that my exhaust backfires like mad? It backfires if I rev it over 2000 RPMS and trust me, they sound like gunfire! Also, which baffles me, is when it idles for ahile it tends to start making popping noises.

Myn does it too, I think it's the TPS or Mixture Solenoid. Dunno why, but I think it's running a tad rich.
