Universal S400 T4 Turbine Outlet Dual V-Band Flange (S400T4FL)

Turbine outlet flange and V-band clamp set for S400 frame turbochargers running a T4 flat, non-Marmon dual V-band turbine housing. It ties the exhaust side of the turbo to a 4" downpipe with a strong, repeatable V-band connection built for high exhaust gas temperature service. This is the turbine outlet flange VS Racing specifies for the Universal 72/89 Billet Gen3 DBB Performance Turbocharger (ST1Z-D45-31T) and other S400 style units.

Choose mild steel for a cost effective weld on flange, or stainless steel for maximum corrosion resistance on a stainless downpipe. The matching V-band clamp is included with either option.
