CNC 4 Cylinder & Rotary Exhaust Manifold Flanges

Please note that the machined side of the flange is intended for welding your tube or pipe straight to it. Once welded the un-prepped (opposite) side will need to be decked (linished or machined) to become flat.

• CNC Machined
• 12mm Mild steel
• As used on our manifolds so perfect fitment

Our CNC milled flanges use the latest CAD/CAM programs which are machined in house on our 3 axis mill. We offer a variety of common aftermarket flanges which are used to manufacture turbo manifolds or can also be used for spacers.
