Scored a catted UPR x pipe for my 95. It's almost brand new and found it locally for $140. In any case, I'm at a loss here. There is no air tube connections for the cats? I see the o2 bungs, but nothing for the air tube. So, those of you who have the catted UPR, what did you guys do to fix this? Did you just plug the tube with a big bolt? If so, will this cause the car to idle rough or hurt the smog pump or anything related? Any help here?
