I have a zpi s-pipe and im wondering, since it has two bungs, (one for the 02 and one for a wideband i believe) if theres anyway to close the 2nd one off with out affecting flow. Since my car is N/A.

If not, does anyone want to buy it from me?

 

if you seal off the one for the wideband there should be no problem whatsoever. I mean you could weld it shut. or did it come with a plug in the hole? If you do put something in there to plug up the hole, make sure you take the necessary steps to help prevent it getting stuck i.e. anti-seize

 

I bought it used, and it didnt come with a plug or anything. Not sure if it ever had one since its made for turbo apps. So i dont really know what i could seal it with.

 

Find a bolt thats the same thread pitch and size. Head to napa.
