Description
The CARGRAPHIC Longtube Manifold Set with 1.75” / 45mm primaries and 100CPSI HD PE Motorsport catalytic converters is engineered to deliver maximum efficiency and performance for Porsche 987.2 Boxster and Cayman models. Designed with equal-length longtube runners merging into a racing-style spliced collector, this system improves power, torque, throttle response, and acoustics. Constructed from SS304L lightweight stainless steel with CNC mandrel-bent pipework and reinforced flanges, it combines precision engineering with motorsport durability.
