This is an exhaust flange that I recommend to all guys building rotary engines.
The flanges are 8.7mm thick, fit securely on 50mm pipes, and have ribs for welding.
Total thickness is 13.5mm.
The welding ribs prevent the flange from warping when creating the exhaust.
Also, unlike flanges that are simply inlayed at the cut end of the pipe, this reduces exhaust resistance and improves efficiency.
This product uses SUS 304.
Since it is a split type, it can be used with all rotary engines including 13B and 26B.
The price is for one flange.
Please order the number of ports.
