Porsche GT3/GT3 RS WC-Sport Headers

Following extensive testing and development at GMG, we are delighted to introduce a groundbreaking enhancement for the 992 GT3/RS. Our newly developed equal-length long tube headers, combined with an HJS 200 cell high-flow catalytic converter, represent a premier upgrade for those seeking maximum power gains, enhanced throttle response, and a richer sound volume, all without the complication of triggering a Check Engine Light (CEL). Key characteristics of this upgrade include:  Construction using premium US-manufactured T304 stainless steel tubing. Intricate TIG welding executed throughout to comply with AWM aerospace standards. CNC-machined flanges expertly designed to avert warping. Simplified installation as a direct bolt-on replacement, guaranteeing no Check Engine lights. An authentic equal-length header design, where each of the six runners is meticulously fashioned to be identical in length within a precision of 0.120 inches.
