Default I Bought a bimmer that is throwing codes

Ok so I bought a 99 323i and the guy said it was his sons bla bla bla. Well he has custom headers so I don't think there is a port for the o2 sensors. So I think the first four is because the o2 sensor isn't connected and the forth I'm hoping is a spark plug or coil pack. My question is will a tune fix the first 4 codes? And if not what are my options??????? The car runs but at idle it bogs down to the point it stalls. All intelligent opinions welcome.

Without the pre-catalysts sensors, you are going to be hard pressed to get an OBDII car to run properly without them. I'm not sure if it is cheaper to have bungs welded into these headers or get factory (used factory) head pipes and restore the pre-catalyst sensors.
Is there a secondary air pump? Is it attached and in working condition. There is an aftermarket air pump simulator that is for sale on the forums.
