Default Header advice please

I am going with some stainless steel headers and ofr y pipe from LLP, which from what I have gathered around here are the SSautochromes. Anyway, I want to go ahead and delete the Air and EGR systems from my 98 z28 A4. I am going through these amazing posts in the sticky and I am not sure if I gathered all the information I need to do this myself.

1. Headers and ofr y pipe
2. Exhaust manifold gaskets and bolts
3. Band clamps
4. EGR block plates

Now, I was wondering what do I do with the o2 sensors after I delete the EGR and Air systems.

You still use the O2 sensors after the AIR/EGR delete unless you get rid of your cats and tune them out.

Yeah I plan to get rid of my cats also, so what do I plug the holes that the o2 sensors were supposed to go.

I don't know what people do. I assume you could either leave the O2's in the hole or weld the hole in. I'm sure someone else will chime in on this.

You can get O2 plugs. Try a local exhaust shop, they should have some. I assume you are talking about the rear O2's?

Block off plates for emmisioins, tune rear o2's out if you need ..... Easy

Thanks guys, I just ordered headers and y pipe from LPP and hoping that the headers are the race style so I don't have to bother with those block plates!!!
