Description
The CARGRAPHIC Longtube Manifold Set with 2x 200CPSI HD OBD2 tri-metal catalytic converters delivers maximum performance and optimized exhaust flow for the Porsche 987.1 Boxster (2.7L / 3.2L) and Cayman (2.7L / 3.4L). Designed as a direct replacement system, it is fully OBD2 compliant and guarantees NO check engine light (CEL) and requires no ECU or DME reprogramming.
Featuring 1.75" (45mm) equal-length longtube primaries, precision-formed on CNC mandrel bending machines, the system ensures a constant diameter for optimal gas velocity. The racing-style spliced collector with spike and large-volume catalytic housings improve flow dynamics, reduce backpressure, and lower operating temperatures.
Constructed from SS304L lightweight stainless steel with reinforced laser-cut flanges and brackets, this manifold system combines strength with weight savings. Dyno-proven gains of up to +16PS (12kW) and +15Nm torque highlight its performance credentials, while the tuned acoustic profile enhances the Porsche flat-six soundtrack without drone or unwanted resonance.
