Manufactured from 12mm 304 stainless steel, our 13B rotary exhaust flanges are perfect for fabricators building high-quality naturally aspirated exhaust headers for Mazda 13B rotary engines.
The exhaust ports are sized specifically to accept commonly available 2″ (50.8mm) OD exhaust tube, making header fabrication straightforward without requiring additional machining or modification to the flange.
Each flange is Australian made, individually finished and QC checked by Metal Sculpt for port dimensions and tube fitment before dispatch.
