2021 Toyota Supra 3.0 Header Flanges
Build your own manifolds!
The release of the 6-port design on the 2021 Supra has been proven to put more power down across the entire power band when compared to last year’s 2-port.
We have developed CNC header flanges that bolt directly to the 2021 Supra. The flanges work with the OEM hardware for an OEM + design.
Extra effort has been put into the design to port match and smooth transitions. Hands down these are the highest quality flanges on the market.
The flanges incorporate a shelf for schedule 40 piping to transition an inside diameter (ID) of 1.610” and an outside diameter (OD) of 1.900” for an exact fit improving weld quality. These dimensions are the exact match for 1.5” schedule 40 piping which is the largest you can fit without any modifications to the OEM hardware.
