I bought some unknown brand longtubes from a dealership that swapped a car back to stock manifolds. There was no name plate, but they looked just like JBA's to me. They have the spike in the center of the collector like the JBA's have too. Not sure if that's exclusive to JBA or not. Well I ended up getting them. But after looking at the catted Hpipe, there are no provisions for rear O2 sensors. I dont know how this is possible. What is the point of having cats, if you dont have the O2 sensors hooked up too. Can anybody shed any light on this? I'm assuming I have to have some bungs welded in.
