Fabspeed Porsche 718 GT4 / GTS / Spyder Long Tube Race Headers (2020+)

The Fabspeed Long Tube Race Headers for the 718 4.0L cars deletes the factory catalytic converters and impressive power gains across the board. Our design process started with 3D scanning the entire exhaust system using our CREAFORM 700 HandySCAN so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After revisions for sound and dyno testing we settled on using 1 7/8 inch primary's compared to the smaller 1 3/4 inch factory primary's. The primaries are mandrel bent using CAD designed model that allows us to achieve the optimal primary length and bends for best flow and scavenging at the collector. The flanges are thick 304 stainless steel that are CAD designed to perfectly match the cylinder heads and reuse the factory metal gaskets.  SOUND: With PSE off our Race Headers give a noticeable increase in exhaust volume with absolutely no interior drone. With PSE on,
