2G Exhaust mani/O2 Housing

[ExTREME]

Basically Im freshing up my DSM and was wondering if anybody knew of a place I could buy a stock 2G Exhaust Mani. with an O2 Housing the cheapest. I'm on a budget if you could imagine and wondering if theres any combo deals out there?

Would I buy a 1G O2 Housing or a 2G? I'm pretty new to the DSM game. I'd like to do my own porting so it already being ported does not matter.

Thanks,
