Catted Exhaust Manifold for Porsche Boxster Cayman 718 Spyder GTS GT4

Upgrade the performance, sound, and driving character of your Porsche 718 with the STRATEC™ Catted Downpipe Exhaust System, engineered specifically for the 718 Cayman, Boxster, GT4, GTS, and Spyder platforms. Designed for enthusiasts who want increased power without sacrificing drivability, this system delivers improved exhaust flow, sharper throttle response, and a deeper, more aggressive tone while retaining catalytic efficiency.

Constructed from premium T304 stainless steel, the STRATEC™ catted downpipe features a high-flow performance catalytic converter that significantly reduces backpressure compared to the factory unit. The result is faster exhaust scavenging, improved mid-range and top-end performance, and a more engaging exhaust note that enhances the naturally aspirated or turbocharged Porsche flat-six experience.

Precision-engineered for OEM-style bolt-on fitment, this downpipe installs directly to factory mounting points with no cutting or permanent modification required—making it ideal for both street and track-focused builds.
