Checkout these killer full taper race style polished solid brass velocity stacks the Wing'd Piston brought back on one of it's many journeys to land of super-cool-hard-to-find-moto-parts!
They're machined from a solid tube of brass for a refined fit and sport a killer finish that goes perfect with a dressed up or turned down motor and carburetor setup.
For easy installation, they have drilled and tapped holes and a set of allen head set screws and take about long as opening the package to mount up. They even come with nice mesh screen to keep that air cooled twin pumping debris free. How cool is that?
