S14 Cold pipe question

[JasonGG]

My cold pipe has the second small pipe coming off the side that would go to the factory recirc valve. Iv gotten rid of it and am looking for something to plug the hole with. Anyone have some ideas? Rather not have to take it out and get it TIG welded shut.

I just get it welded shut so you won't have any small boost leaks later on down the road.
The welding shop shouldn't charge much, check around. Good luck!
