Description
The CARGRAPHIC Longtube Manifold Set with 2” / 50.8mm primaries and 200CPSI HD OBD2 tri-metal catalytic converters is designed for maximum performance while maintaining full road compliance. Built with equal-length longtube runners and a racing-style spliced collector, this system improves gas flow, torque, throttle response, and acoustics without triggering fault codes. Constructed from SS304L lightweight stainless steel with CNC mandrel-bent pipework and reinforced flanges, it offers durability and precision engineering.
