Description
The CARGRAPHIC Longtube Manifold Set with 1.75" (45mm) equal-length primaries and 200cpsi HD OBD2 Tri-Metal catalytic converters is designed to maximize performance and sound for the Porsche 981 Boxster and Cayman models. Built with motorsport precision, it optimizes exhaust gas flow, reduces backpressure, and enhances throttle response—all while remaining fully OBD2 compliant with no CEL or ECU/DME programming required.
Engineered from SS304L lightweight stainless steel with CNC mandrel-bent construction, this manifold set delivers measurable power gains, weight savings, and a sharper, crisper exhaust note that remains true to the Porsche character.
