PowerPipe Exhaust for slant/6

Hey Don, I am going to go the 'dual exhaust' route on my 70 Swinger. I dont know but I just cant see all that work into getting two headers then making them one again. To me it kind of defeats the purpose of dual exhaust. I know like I said, people I know with headers have gone this single route but for me its something different as usual. Hows the progress going on the headers by the way?
