SMX Exhaust Turbo Flange for Volvo D4
These are the finest quality exhaust flanges you can get————-Investment cast SS316L and machined to +/- .001”.. Extra heavy duty “weld boss” section to 100% prevent warping when welding. Designed to use with or without a gasket (we prefer a coat of high temp silicone on the mating surfaces to the turbo and anti-seize on the Marmon/V-band clamp bolt). 1/8” NPT Pyro Probe / Test Port is pre-drilled and tapped and includes a brass plug.
