AWR Header
 

Hey guys im thinking about getting these headers from AWR....

only problem is... i dont know where to relocate the o2 sensor... does anyone know how or someone who has?

Well looking at those headers. Theres no place to put an o2 sensor. So what i think you should do is to get a aftermarket cat to replace the one under your car. But have the company that made the aftermarket cat put two threaded holes for your o2 sensors. One in the front of the cat and one in the back of the cat. Your going to have to extend the wires of your o2 sensor. I want to put the mazdaspeed hearders on my p5 but im short on cash. My brother had the same problem when he need to put his headers on his 98 200sx. He used a aftermarket cat from Random Technology. Hope this helps.

Do a search on the AWR header...

There was a thread that mentioned an email from AWR, and that it did contain a hole for an o2 sensor. You would still need to fabricate one for after a catalyst though...
