Unlock the performance potential of your 2012-2015 Mercedes-Benz GL450 or GL550 W166 with our GCA Performance Downpipes, engineered specifically for the powerful M278 4.7L Twin Turbo V8 engine.
Designed by German Car Accessories under our GCA Performance lineup, these high-flow downpipes are built to improve exhaust efficiency by increasing airflow and reducing back pressure. This allows the twin-turbo V8 engine to breathe more freely, improving throttle response, turbo efficiency, horsepower, torque, and overall driving performance.
Constructed from high-quality T304 stainless steel, these downpipes are designed to withstand extreme heat and demanding driving conditions while maintaining long-lasting durability. Precision TIG welding ensures superior strength and perfect fitment for a clean installation.
Whether you are building a performance-focused Mercedes SUV or looking to enhance the sound and response of your GL450/GL550, these downpipes provide the ideal upgrade for the M278 V8 platform.
