Talked with Vance & Hines (2 different techs, called 2 different times and asked the same question) and they both said their pipes will not fit, also a tech from BUB said the same thing. V&H said the Big Shot for the Marauder would be out in November some time. The model specific part # on my Marauder pipes are kaw4291500 and kaw4291600, which I would think would mean the same pipe for the mean streak 1500 or 1600 and yes that is the # stamped directly on the pipe. I was at a Kaw dealer and looked at a 1600 mean streak and the same model specific part #'s were on those pipes as well.......kaw4291500 and kaw4291600.. looks to me that any pipe that fits one should fit the other, but I don't want to order them and the seller not take them back if they don't fit. SO this being said has anyone actually put aftermarket pipes on ther Marauder, if so, which ones did you use, and how did they fit. I would love to see pictures if you could post them.
