I am looking for headers I am runnig a hsr fuel injection, I am looking for 1 3/4 inch primary and 3inch collecters, and was wondering which have 02 sensor provisions?
i hav looked at hooker 2210 long tube headers but i dont know if they have 02 sensor provissions

 

you can always have the o2 bung welded in. pretty sure its not a big deal and shouldnt cost much.

 

I'll never do longtubes again.....new motor mounts/ tranny mount and will never be able to lower the car...
