The system incorporates GMG's proprietary cross over center section which has been engineered for maximum efficiency with a specific center chamber that equalizes exhaust pulses and offers a scavenge effect to speed up exhaust flow. The sport mufflers utilize the latest design and material offering minimal restriction while maintaining maximum sound absorption throughout the rev-range and are made with stainless steel packing throughout.
