After several months of rigorous testing, GMG is thrilled to announce the launch of our new over-axle pipes for the GT4RS. These pipes are expertly crafted from premium 304 stainless steel and feature HJS 200 cell high-flow catalytic converters, delivering notable enhancements in performance. Our comprehensive development process has established that these over-axle pipes significantly boost performance, delivering an increase of 7 WHP and 5 lb-ft of torque. They also enhance responsiveness across the full power spectrum. Furthermore, the over-axle pipes are fully modular, ensuring seamless integration with factory headers and exhaust systems, and they are designed to avoid triggering the Check Engine Light (CEL).
