Himni Racing exclusive design 13B rotary engine header / manifold exhaust flange. Unlike other cast, small bore stainless engine flanges that restrict flow, the HR SS engine flange is CNC machined from solid 1/2 inch thick 304 stainless steel billet stock & has large 2 1/8 inch (2.125")I.D. runner bores. The same flange used on our turbo manifolds & is ideal for any DIY fabricator looking to make their own custom header / manifold that requires maximum flow. Designed with lots of 'meat' between the runner bores to prevent curl up warping when subjected to heat & welding... A must for a leak free seal.

Fits all 13B 2 rotor rotary engines:
13B N/A, 13BT, 13BTT/13B-REW, 13B-RE Cusmo, GSL-SE, S4 / S5 (86-91) FC3S RX7, S6 (93-00)FD3S RX-7
- USA Made, CNC Machined, Durable, Leak-Free sealing
- Large 2 1/8" high flow bore prevents exhaust pulse restriction
- Bore size can be increased/decreased w/ tube transitions
- Outstanding surface area promotes a true surface when subjected to heat
- Full 1/2" (.500) thick 304/304L SS (Superior to Mild steel, stronger & will not rust)
- Used to make non-turbo header or turbo manifold
