I'm about ready to go ahead with replacing the stock exhaust. was looking for a thread explaining what else needed to be removed/blocked off etc. to make it work. I couldn't find anything here or on atkins or RB sites either. I have a rotatary engineering header and a universal 2.5 in. racing beat muffler that I plan on building the system with, along with tubing and gaskets, what else will I need?

Racing Beat has a PDF instruction manual on their website. I would expect your Rotary Engineering header installation procedure to be pretty much the same.
thanks, that says to remove air pump and associated parts, that's about it for a 79, but there is metal tube that connects from the exhaust to something between the firewall underneath the carb. does this get blocked also?

I'l buy your stock exhaust dingleberries from you .
right now I'm assembling everything I'll need to get it done. it may be spring before I get to it as I don't have an enclosed garage. the muffler is in good shape, manifold probably too, everything else is toast pretty much
it may happen sooner than I thought as I think I blew out the muffler last night. it was running good on the way to Quincy and back and then it started loosing power and backfiring through the exhaust with the tach bouncing around erratically too. I managed to limp home the last 30 miles at 30-50 mph, but it was tense. I changed the plugs today because that seemed to help last time it ran like this, and it seemed to run ok going around the block, but there must be something else going on in the ignition with the tach bouncing around like that.
