need some help with my header install
SO i am going to install a set of obx headers on my car next week and i am finding some conflicting info on some things.
First what exhaust manifold gaskets do i use. I have found anywhere from using the old metal ones to using aftermarket non metal ones.
What should i do with my o2 sensors. I have read to either remove the rear and use them upfront or to just keep them the same.
If i keep them the same do i still need extensions and if i just use the rear in the front what do i need?
Its a 99 6sp vert if that matters
Thank you

I just installed them last weekend. I got a pair of 99 camaro z28 exhaust manifold gaskets from the chevy dealer. I used my rear o2 sensors for the front but I had to get some adapters. Btw, my rear o2 ports were already plugged, so I didn't have to worry about that.
Here is the adapter

Can't beat the GM gaskets for the headers, but the earlier gaskets have the ports required for the headers. If you move the rears, you need adapters. When I did this (don't currently run this setup) I bought a couple of high quality stainless clamps and put two longer bolts into the tunnel plate so I could mount the clamps. Then I used the clamps to take up the excess length so the wires wouldn't hit the headers.
