Product Information
Experience the full character of your Mercedes-AMG G63 W463 M157 5.5L BiTurbo with the BlackBoost Straight Pipe Valved Cat-Back Exhaust System. Designed for enthusiasts who demand uncompromising performance and an unmistakable exhaust note, this premium exhaust system delivers maximum airflow, reduced turbo back pressure, and impressive power gains while offering the flexibility of adjustable exhaust sound.
Developed using advanced CAD modelling and Computational Fluid Dynamics (CFD), the BlackBoost exhaust system is engineered to optimise both exhaust flow and acoustic performance. Featuring a full 3-inch mandrel-bent SS304 stainless steel construction, it eliminates unnecessary restrictions to help your twin-turbo V8 breathe more efficiently, improving horsepower, torque, and turbo response.
The integrated vacuum-actuated exhaust valves allow you to switch between two driving experiences. With the valves open, the system delivers an aggressive straight-pipe exhaust note that fully unleashes the sound of the M157 BiTurbo engine. When the valves are closed, exhaust gases are redirected through the specially engineered rear muffler, providing a quieter and more refined driving experience suitable for everyday use.
Built entirely from premium low-carbon SS304 stainless steel, the system incorporates laser-cut flanges, precision mandrel bends, SS316 corrosion-resistant exhaust valves, and ceramic ball-bearing valve mechanisms for smooth, reliable operation and long-lasting durability. Tested to support vehicles producing over 1,000 wheel horsepower (WHP), this exhaust is equally at home on daily-driven SUVs and high-performance builds.
Whether youre looking for a more aggressive soundtrack, increased engine efficiency, or the perfect foundation for future performance upgrades, the BlackBoost Straight Pipe Exhaust System delivers exceptional craftsmanship and proven results.
