Vibrant Mild Steel Exhaust Manifold Flange for Honda/Acura B-Series motor 1/2in Thick

If you're building a custom exhaust for your Honda or Acura with a B-Series engine, this mild steel exhaust manifold flange from Vibrant is a solid starting point. It's precision laser cut from 1/2 inch thick HRPO mild steel, giving you a strong base for fabricating a new exhaust manifold or connecting to your existing setup.

The exhaust port size on this flange is optimized for either standard wall round tubing or Schedule 10 weld fittings, making it easier to get a good fit when you're welding. Vibrant recommends using 309L welding rod if you're joining it to 304 stainless steel pipe, which is a good tip to keep in mind for a strong weld. This flange is designed to work with Schedule 10 or Schedule 40 pipe, offering flexibility in your build.
