Unlock the full potential of your 2016-2019 Mercedes-Benz GLS63 AMG W166/X166 with our GCA Performance Downpipes, engineered specifically for the powerful 5.5L Twin Turbo V8 M157 engine.
Designed by German Car Accessories (GCA) under our GCA Performance line, these high-flow downpipes are built to improve exhaust flow, reduce back pressure, and optimize turbo efficiency. The result is stronger horsepower and torque delivery, sharper throttle response, and a more aggressive V8 exhaust character.
Manufactured from premium T304 stainless steel, these downpipes are designed to withstand extreme temperatures and demanding performance driving while maintaining long-term durability. Precision TIG welding ensures maximum strength, accurate fitment, and reliable performance.
