STM Stainless Steel Exhaust Manifold Head Flange for 4G63 Evo/DSM

This 304 stainless steel STM exhaust manifold head flange fits all Mitsubishi 4G63 heads including Evo 1-9, 1G/2G DSM and GVR4 models.

The flange is machined with a recessed oval port that accepts 1.5" schedule 10 pipe once it has been shaped and stretched. Doing it this way does take more time and gives you less options for runner routing, but in the end, it makes a better finished product with the smoothest transitions possible.
