Vibrant Mild Steel Exh Manifold Flange for BMW E36/E46 platform motors (sold in pairs) 1/2in Thick

If you're fabricating a custom exhaust system for your BMW E36 or E46 platform vehicle, these mild steel exhaust manifold flanges from Vibrant Performance are a solid starting point. These are designed to be welded to standard wall round tubing or Schedule 10 weld fittings, giving you a strong base for building your own headers or exhaust manifold. They're precision laser cut from 1/2 inch thick HRPO mild steel, which provides a substantial surface for welding and helps ensure a good seal against the cylinder head.

Vibrant Performance offers a wide variety of exhaust manifold flanges, and these are optimized for exhaust port sizing to help improve flow. While these flanges are made of mild steel, they are suitable for use with stainless steel piping. The manufacturer suggests using 309L welding rod when joining 304 stainless steel to these mild steel flanges to ensure a strong, lasting weld. This pair of flanges is sold as a set, ready for your custom fabrication project.
