Unlock the performance potential of your 2016-2019 Mercedes-Benz GLS550 W166/X166 with the GCA Performance Downpipes from German Car Accessories. Designed specifically for the 4.7L Twin Turbo V8 M278 engine, these downpipes improve exhaust flow, reduce back pressure, and help your GLS550 deliver stronger and more responsive performance.
Manufactured from high-quality T304 stainless steel, these downpipes are engineered to withstand high temperatures and demanding driving conditions while providing long-lasting durability. The optimized design allows exhaust gases to flow more efficiently, improving turbocharger response, throttle feel, and overall power delivery.
The factory exhaust system can restrict airflow, especially on modified or tuned vehicles. By increasing exhaust efficiency, these downpipes help maximize the potential of the M278 Twin Turbo V8 while providing a stronger foundation for future performance upgrades.
