Porsche Sport Headers For Porsche 981 Cayman GT4 (2016) Models.

Embrace Everyday Performance and Enhanced Sound with Emissions Compliance

Experience the perfect synergy of low-end power gains and a more aggressive sports car sound that you can enjoy on every drive, all while maintaining emissions compliance. These Fabspeed Sport Headers are the ideal upgrade, whether paired with the factory exhaust system or our performance exhaust systems. Designed around premium HJS German-imported, European certified, and European homologated catalytic converters, they offer the best solution for a more engaging street driving experience without sacrificing emissions legality.

Engineered with a focus on noticeable street performance, these Sport Headers deliver an impressive additional 26 wheel horsepower (whp) and 39 ft/lbs of torque at 3600 RPM. This translates to significantly improved acceleration from a standstill and enhanced throttle response when merging onto the motorway or enjoying your favorite winding roads. Thanks to the world-class performance of the EMITEC trimetallic HJS catalytic converter cores, your GT4 will remain emissions-compliant in most regions and will not trigger a Check Engine Light (CEL).Beyond the tangible performance benefits, Fabspeed's GT4 Sport Headers also enrich the exhaust note, increasing the overall volume and adding a more characterful and engaging tone.

• Premium Catalytic Converters: Includes German-imported 200-cell HJS Sport Catalytic Converters, ensuring maximum performance and long-term reliability.
• Significant Power Gains: Adds +28 HP and +41 ft-lbs of torque at 3600 RPM, providing noticeably better performance during everyday street acceleration.

Be cautious of other US-based companies claiming HJS catalytic converters, as they may be sourcing grey market, black market, or even counterfeit units, potentially leading to no warranty and financial loss.
