Description
The CARGRAPHIC Longtube Manifold Set with 2" (50.8mm) equal-length primaries and 100cpsi HD PE MS catalytic converters is designed for maximum performance on Porsche 981 Boxster and Cayman models. Engineered for track use and export applications, this system delivers extreme flow, reduced backpressure, and sharper throttle response.
Note: This version is NOT OBD2 compliant. ECU/DME reprogramming is required for proper operation (except for 981 Cayman GT4 Clubsport models, where no ECU adjustments are needed).
Manufactured in Germany from SS304L lightweight stainless steel with CNC mandrel-bent construction, reinforced laser-cut flanges, and racing-style collectors, this manifold set is built for high-performance durability and maximum gains.
