This is a 3D model of an exhaust header manifold flange.It includes the end part of the exhaust header which converges the gases from all 4 exhausts to a single output that drives that turbine wheel.It is custom designed for a 4 cylinder header and can be modified according to your needs if required.Please feel free to contact me if you need any modification or other versions.Size is random but can be scaled to whatever size you wish. Along with the native Solidworks file, you can also find parasolid, iges and step formats as well as stl, amf and 3mf. Polygon file is also attached. Can be used for 3D printing.
