Unlock the true performance potential of your 2013-2018 Mercedes-Benz G65 AMG with the GCA Performance Downpipes from German Car Accessories. Specifically engineered for the W463 G65 AMG equipped with the 6.0L Twin Turbo V12 M279 engine, these high-performance downpipes improve exhaust flow, reduce back pressure, and help your AMG V12 deliver stronger power and quicker turbo response.

Manufactured from high-quality T304 stainless steel, these downpipes are built to withstand extreme temperatures and demanding driving conditions while maintaining long-lasting durability. By reducing exhaust restriction, they allow the twin turbochargers to spool more efficiently, improving throttle response, horsepower, torque, and the aggressive exhaust note expected from Mercedes-AMG's flagship V12.

Designed as a direct bolt-on replacement, the GCA Performance Downpipes utilize OEM mounting locations for precise fitment and can be returned to stock at any time. Whether paired with a factory exhaust or a complete performance exhaust system, these downpipes provide a significant improvement in overall engine performance.
