CARGRAPHIC high-performance header for Porsche 991 Carrera 4 und Carrera 4S

More power through motorsport technology for Porsche 991.1 Carrera 4 3.4l / Carrera 4S 3.8l

The CARGRAPHIC header, specially developed for the Porsche 911 Carrera 4 and Carrera 4S models of the first generation of the 991 series, offers a primary pipe diameter increased to 2" or 50.80mm compared to the series exhaust manifolds, as well as both identical and extra long pipe lengths. Due to the precisely calculated design, the exhaust gases are thus led out of the cylinder without significant back pressure, which means that the piston requires less force to expel the exhaust gases. The resulting faster and complete replacement of the exhaust gases with fresh gas leads to optimised combustion, a lower internal cylinder temperature and less effort, and thus to a noticeable increase in performance.

Fully made from SS304L Lightweight Stainless Steel on CNC bending machine

CARGRAPHIC manifolds are high precision, high performance exhaust components and are made entirely of SS304L lightweight stainless steel. The production with modern CNC pipe bending machines with mandrel support (Mandrel-bent) allows a continuous constant pipe diameter. Laser-cut flanges also ensure outstanding fitting accuracy.

Manifolds with integrated catalytic converters

CARGRAPHIC high-performance header for the Porsche 991.1 Carrera and Carrera S is also available with integrated CARGRAPHIC sport catalysts. Different versions are used depending on requirements and application: 200 cell tri-metal honeycomb carriers with full OBD2 compatibility or as 100 cell MOTORSPORT versions for individually tuned performance upgrades.
