I have coated headers with A.I.R I kind of want to remove that system but keep the EGR.

 

post #14 has it right... Pipe cap..Cheap, and quick. works great

 

I welded mine closed!

 

on the caps, my threads are on the outside for the AIR on my pacesetter headers, does anyone carry ceramic coated caps to fit over the AIR? My friends headers on his 94 were pacesetter and the threads were on the inside, so we used a M22 oil drain plug, I wish I could use a M18 oil drain plug but with the threads on the inside of the cap.
