Maximize Exhaust Flow and Engine Response on Your Porsche 718 Cayman GT4 RS 4.0L with Catless Racing Headers
Designed for the Porsche 718 Cayman GT4 RS with the 4.0L naturally aspirated flat-six engine, these catless racing exhaust headers replace the restrictive factory manifold and catalytic sections with a free-flow performance design engineered to improve exhaust gas flow and reduce restriction.
Manufactured from high-quality 304 stainless steel, the headers feature integrated thermal heat shielding to help manage temperatures around the exhaust system. The catless configuration eliminates the factory catalytic restriction, supporting sharper engine response, improved exhaust flow and a significantly more aggressive flat-six exhaust character.
Compatible ECU calibration is required after installation for correct operation with the catless configuration. Professional installation is recommended to ensure correct alignment, sealing and integration with the existing exhaust system.
