Description
The CARGRAPHIC Longtube Manifold Set with 2" (50.8mm) equal-length primaries and 100cpsi Inconel MS catalytic converters is designed for maximum flow, extreme durability, and reduced weight for Porsche 981 Boxster and Cayman models. The use of Inconel-based motorsport catalytic converters provides superior heat resistance and weight savings compared to stainless steel versions, making this the ultimate choice for demanding track applications.
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).
