Competition Link Downpipe
Fabspeed's Cat Bypass Pipe with Downpipe for the 718 Boxster and Cayman (Base/S Worldwide 2017+, GTS 2017-2020) is a direct bolt-on replacement for the factory catalytic converter and downpipe, using mandrel-bent T304L stainless steel 3-inch tubing that splits to 2-inch for maximum flow while keeping proper exhaust gas velocity. Expect a significant jump in volume, with cracks and burbles on deceleration, especially in Sport mode, plus a stronger turbo spool sound that can be pushed further with Fabspeed's Maxflo exhaust. Fabspeed estimates 25whp on its own, with more available paired with a Fabspeed ECU tune. Because it removes the catalytic converters, this product is intended for closed track and off-road use only, not for public roads, and requires signing Fabspeed's Vehicle Compliance Waiver before purchase.
