your in the wrong section, but i'll attempt to help you out.
if your trying to soup up your car, i would recommend progresso, as campbells isnt as fufilling, and it has a larger size can.
ultimately, you should get coffee instead of soup, and a good brand for that is folgers. a whopping 6'' diameter muffer should net you around 50 hp.
here are some directions to the coffee muffler.
