The new Granatelli Motor Sports V-Bands use a unique interlocking designed and are made of 6061 aluminum on intake side with gasket and high-quality 304 stainless on the exhaust side. For exhaust needs Granatelli’s new oval tube provides more exhaust flow and its available in different configurations for more clearance. Granatelli’s new exhaust cutout uses a one-touch switch that fully opens or closes the valve so it doesn’t stress the cutout’s gears.
