What part number do you guys use. I can't find an exhaust for my foreman anywhere. The only one that I could find that might fit is for the rubicon 500. Is this the one that you guys ordered. I don't want to order something and have it not be the right one. Also the hmf website said that it take a couple of weeks to build your pipe. Do you have to buy it from them or is there some place that has that pipe already in stock ready to ship.
