Yup, the ProChamber has a port to connect the emissions hose. But you won't be able to mate BBK headers to a MAC ProChamber. They're bent to mate up to their headers only so you'd have to modify things to get them lined up.
I've used MAC headers since the early 1990's and haven't ever had a warped flange.

you get a little more HP with the pro chamber, but I personally like the sound of the H pipe. pro chamber is pretty much the same thing as the H pipe just another chamber to go through.
With the HP+ for the pro chamber thats what I was told, never had one

Thanks for starting this thread. I recently took a trip back to the states for a few months and purchased an '89 LX. However, I'm back in Japan now for another year. Listening to your car every day or so is helping me make it through this next year without my baby. That clip reminds me of watching Gone in 60 Seconds while Elanor is on the prowl. I can't wait to get back and drive her once again. Thanks for the thread and all the great info.
