Description
The CARGRAPHIC Longtube Manifold Set with 100CPSI HD Inconel PE catalytic converters is a high-performance motorsport manifold system for Porsche 991 GT3, GT3 RS, R, and GT3 Touring models. Designed for maximum exhaust flow and minimal backpressure, this set enhances torque, throttle response, and exhaust acoustics. ECU/DME reprogramming is required as this version is not OBD2 compliant.
