42 Draft Designs now offers v-band connection flanges with the stainless steel exhaust systems. Compared to 3-bolt flanges, exhaust systems built with v-band flanges are easier to install and adjust. V-band connections don't require a gasket, and can be serviced with a single tool. Overall, v-band flanges speed-up initial install and race-day component changes.
These V-band flanges are CNC machined from 304 stainless steel. Using a male/female fitment specification for the flanges aids in sealing the connection. Due to the material cost and manufacturing time, v-bands will remain a premium option.
