    F/S GPR Factory Pipe Expansion Chamber Exit Reducers

    F/S GPR Factory Pipe Expansion Chamber Exit Reducers
    $75 + shipping. 6061 T6 precision CNC machined. They are 28mm ID with a taper into the pipe. Dimensionally, these are the same reducers installed in my Superstock. I think TJ designed these back at Riva. They are very durable and never get jammed in the pipe exit like others I have seen.
    I was contacted by a member to find out if I had some of these, but I ended up making a set for him. While I was at it, I made 3 sets. So I'm selling the 2 extra sets. I can open them up to about 30mm if you want. Thanks for looking.
    >>4/14/09 Ordered more material. Will have plenty of them ready next week.
    I have the parts ready. Please pm me if you want them.
    Thanks for looking, JV

    Stinger inserts

    Pat, Check your pm.
    If you have a any system that lowers the back pressure like a Factory Pipe Downstream Muffler, these are required and came with the Factory Pipe kit.
