HDI Marine's Exhaust Riser Extension 7" Cast 316 (HDI GMR7) is a high-grade stainless steel exhaust component designed for serious marine parts installations. This 7-inch extension raises the exhaust intake port by 6 inches, delivering extra clearance for your boat’s exhaust system. Cast from 316 stainless steel for corrosion resistance, it offers robust performance in harsh marine environments. It’s listed under the Exhaust Components category and branded by HDI Marine, a trusted name in boat parts.
Designed to integrate with standard exhaust layouts, the 7" riser extension improves airflow and reduces heat and vibration at the outlet. It’s a practical enhancement for performance-minded vessels and is suitable for a range of hulls and configurations. As part of marine energy systems, this exhaust component helps protect engine compartments and prolongs service life.
