What's this tube on my OBX Header (Passenger side)?
 

I bought a lightly used set of OBX headers and they are somewhat installed.

On the passenger side there is a tube and I'm not sure what it's for, and what I need to do with it. It's 3-4" long, about .75" diameter, attached to one of the primary tubes, pointing towards the front of the car.

I can post a pic if necessary.

I have removed the air pump, so if it's related to that, I guess I need to plug it. If so, any suggestions on how folks have plugged it (other than removing the header and welding a plug)?

Thanks.

It's probably for the air pump. I believe a 3/4" NPT (pipe) plug will fit. - Steve

Thanks, Steve.

Yep mine is blocked off.

Russ, is that just left open?
Doesn't look threaded. Not sure how you'll plug that.

You're right, there are no threads. I could create threads but I'm probably going to remove the header and plug the hole via weld.

That would certainly be the best option.

Why wouldn't you just "sweat" an appropriate cap over the tube or in the tube so as not to defeat it's purpose if resale ever became something you desired?

Re: What's this tube on my OBX Header (Passenger side)?
 

I'm not too familiar with "sweating", but that's probably a good idea (to save the functionality). Thanks. I'll ponder how I might do that.

Re: What's this tube on my OBX Header (Passenger side)?
 

Sweatings not difficult. Scuff, flux, heat and solder.
Dave, how hot do the headers get? Wouldn't solder melt off (think it's 400 degrees to melt, could be wrong though). Brazing would be better I would think.

Re: What's this tube on my OBX Header (Passenger side)?
 

I believe that maybe someone has taken "sweating" just a little to literally and maybe I should have mentioned "brazing" but this rod is similar to some that a friend uses. This is a very short video and you can see the quality of the finished seam.

Take a look at their SSQ-6 paste.

I'm quite sure he doesn't use the MuggyWeld product but he could very well use it.
