These pipes came off of an 05 polaris 900 with a struthers 975 kit. As far as i know these pipes were prototypes and only about 6 sets were built (i don't know for a fact) includes pipes, stingers, flanges, and a dobeck performance/ boss noss fuel adjuster. I don't have any of the hardware (springs, bolts, gasgets,) $450 and i will pay for shipping in cont. US. If interested please pm or call justin 406-261-2337
