i have the same pipes, if im not using one of those bov flanges whats the best way to plug it up? should i have it cut and welded?

 

Well you might not like how I plugged one of mine....

I slipped a short piece piece of 1" tubing over it, and clamped a copper 3/4" endcap, inverted, inside the tubing...(the endcap is too big to fit through the hole) hasn't moved in years...

 

turbo xs rfl bovs come with a plug,i might have 1 some where.

 

that would be cool, im going to cut one of the flanges out to have my greddy flange welded on and then plug the other, so if you have that plug that would be awesome
