I am trying to squeze as much power out of my flathead six on my old B1PW. And since I have a 50$ gift certificate from Vintage Power Wagons that I won at the CA. Hollister Rally, I thought I would put it towards a duel exaust manifold. Does it really HELP out in the horsepower? And does anyone out there have one for sale so I can use my gift money for something else. Thanks Paul in Grass Valley CA
