A M20 exhaust manifold flange for you to DIY your own turbo piping.
Port diameter is 36mm;
12 mm of thickness;
Mild steel or 304 stainless steel;
Please note that the due to the laser cutting and the specific pattern a slight bend forms. You can use a shop press to minimize its curvature. Furthermore when fabricating a manifold it is advisable to use a solid flat base to hold it while welding the tubing. After that it is highly recommended to have the sealing face machined to achieve a flat surface before installation – failing to do so might cause cracked welds and shorten the life span of your manifold.
