    Default 1989 gb500

    I was wondering what supertrapps you have for this bike and what info you have on the original white brothers build in 1990 of this same bike, ie: what set of pipes they used and do you still make those

    The GB500 slip-ons were discontinued in '02, all design specs & welding fixtures were disposed of to make room for new models. The mufflers used for the slip-ons were from our SuperLight Stainless Series (Universals).
    White Brothers purchased a lot of our 4" Aluminum Racing Series Universals, for different applications, and adapted them to connector and head pipes which they developed.
