Couldn't find any info on this in search so here goes sorry if a just pass out old info. Saw this in another forum so decided to try it myself. Warrior pipes will fit the Raider by making a new rear mounting bracket and adding a O2 sensor bung. Other than that they will bolt right up. I have installed a set of V&H Big Shots myself and have heard of another guy using the Samson Street Sweepers. Thats all I know of at the moment but there will be more likely as time passes.
