Our exhaust manifold flange is made from 3/4" x 4" 304L stainless steel.
It is 16mm thick and designed for 1.5" schedule 10 pipe (inquire about different size tubing for your project).
The ports transition from square to round and feature a recessed pocket for your pipe/tubing to speed up the fabrication process, eliminating the need to shape pipe to match the port.
The flange is designed to minimize warping.
This flange fits big port heads that use the exhaust manifold gasket part numbers 03H-253-050-D 03H-253-039-H
