I ordered a DC ceramic header (GSR 4-2-1) for my LS/vtec setup. What do I do about the o2 sensors!?

 

what do you mean?
you just screw it in like the stock header
im using a dc and it works fine.

 

the 02 sensor has a plastic clip that can be unhooked. When you pull the old header leave the 02 sensor in and then unbolt it once everything is out. Snap-On makes a special socket for it but you really only need a wrench.

 

There are 2 o2 sensors on when running a PR3 ecu. The DC header only has a spot for 1! Where does the other one go?>

 

in the catalytic converter prolly.......
