Shuken Racing zoomies are built using the highest quality materials and fixture welded to ensure quality. We start with lightweight CNC machined, (not flame or laser cut) flanges and smooth, wrinkle free mandrel bends. We double weld the tubes, which creates a strong, but flexible joint which eliminates the need for a plate gusset. Zoomies are available for Big Block and Small Block Chevy with standard or spread port flanges, in various tube diameters. Call 559-250-2641 to place your order today!
