The angled shreadstack was designed by Rodney Shreadhead Ketchem to replace the stock plastic HPI Baja 5B/SS/5T filter base. The angled shreadstack will angle your filter above the gas tank for easy install and removal. The shreadstack is more reliable then the stock filter base and the built in v-stack will give you motor a little more power. This stack allows for a higher torque on the carb bolts for better gasket sealing. This is a billet stack so the higher torque on the carb bolts will not bend or warp this stack. This stack requires all of your stock HPI filter components except for the base.
