Header Plug?
Hey - picked up some used headers the other day for $50. Figured they were worth a try. They look fine, but there's an approx. 3/4 inch hole down near the collector on the driver's side for what I assume is some emissions thing. How can I plug this without welding?
Would something like this work? http://www.jegs.com/i/JEGS+Performan...00454/10002/-1

Re: Header Plug?
Threaded?
Probably for an O2 sensor, should take a 1/2 NPT plug available ay most any parts store.

Re: Header Plug?
O2 sensors aren't 1/2 NPT, they are metric IIRC. You can buy a plug that screws right in... or just thread in an old O2 to plug the hole.

Re: Header Plug?
Thanks. I'm not sure what the heck I was thinking about.
