Fabspeed High-Performance Exhaust Headers for Porsche 996 Carrera (1999–2004)

Description

The Fabspeed Sport Headers for the Porsche 911 (996) Carrera and Carrera 4 (1999–2004) are high-flow exhaust manifolds engineered to unlock more performance and a richer exhaust note from your flat-six. Replacing the restrictive factory cast manifolds with mandrel-bent T304L stainless steel headers, this upgrade dramatically improves exhaust scavenging and flow efficiency — translating to sharper midrange torque, stronger throttle response, and a more aggressive exhaust character. Designed and tested for both street performance and compatibility with aftermarket exhaust upgrades, these headers are a popular performance milestone for enthusiasts seeking a noticeable step up from stock.
