Exhaust question... installed h-pipe.

[Mr. B]

I bought a used BBK o/r h-pipe and installed it on Friday. The factory pipe was tied into a long tube that runs just above the passenger side of the h-pipe and then up above the header. There it's bolted to the block with a bracket and tied into a black plastic valve with a hose and clamp.

Obviously the o/r pipe isn't setup to tie back into this tube. So my question is... what is the tube and is there a proper way to cap it off? My guess is that it's something to do with the EGR system, but I'm not sure. Should I cap it off under the car, or take the whole pipe out and cap it off at the valve in the engine compartment?

im in the process of this right now. i dont know if u would consider it to be the right way but i got rid of that tube and the tube that connects to the back of the heads im just going to block off the holes with 9/16 bolts seems to fit right in there. i also got rid of that plastic hose with the valves and junk and got rid of the smog pump. no emissions here i have not finished yet but my old car was done this way and seemed to work fine.

Smog pump... that's it!

But where the tube connected to the old h-pipe there is no way to cap it off with a bolt. It was a slip in connection with a clamp before. I think I'd rather just leave the smog pump and everything there and just cap the tube off. That way I can put everything bac kfor inspections.

i know exactly what your talking about but im not sure what the best way would be its not easy to get that pipe out of there so i would be trying to cap it some way.

I capped mine and ended up causing the smog pump to fail... Now i have a shorted belt just bypassing it. I'd say either get it welded in or get ride of it all together.. I'm still working on the getting rid of it altogether thing.
