Transform the sound and response of your 2021+ Mercedes-Benz S580, S580 Maybach, or S580 Brabus W223 with Redstar Performance M176 downpipes. Engineered for the M176 4.0 biturbo V8, these downpipes replace the restrictive factory sections immediately after the turbos to deliver the distinctive AMG-style V8 character with pronounced burbles and crackles.
By reducing backpressure and improving exhaust flow, the Redstar system unlocks significant power gains with faster spool and sharper throttle response. Lower exhaust restriction also supports turbocharger longevity, while optional OEM-style heat shielding cuts radiant heat by up to 80% to help protect nearby wiring, hoses, and components and reduce under-bonnet temperatures.
Built for durability and seamless integration, each system is produced from 3 inch, 2.0mm wall 304 stainless steel, fully TIG welded and back purged with OEM-spec 304 stainless steel flanges. It is a true bolt-on upgrade that mounts using factory-style brackets, and is LHD/RHD compliant. Available with high-performance HJS HD 200cpsi or GESI GEN2 400cpsi catalytic converter options, Redstar downpipes deliver precision construction, long-term reliability, and the unmistakable Redstar performance exhaust tone.
Available Options
- HJS HD 200cpsi Catalytic Converters: Engineered in Germany and trusted worldwide, the HJS 200cpsi ultra high-performance cats are rated for over 1000hp. Renowned for exceptional flow, durability, and consistent quality, these converters set the benchmark for high-output applications. Ideal for drivers demanding maximum performance without compromise.
- GESI GEN2 400cpsi Catalytic Converters: The latest GEN2 series from GESI is rated to support up to 1000hp while offering smoother exhaust flow and improved efficiency compared with factory units. Featuring advanced emissions technology for optimal catalyst function at high flow rates. A strong choice for those seeking significant performance gains with refined operation.
- OEM-Style Heat Shielding: Redstar's signature thermal management system reduces radiant exhaust heat by up to 80%. Developed with motorsport-inspired materials and construction, it uses a multi-layer design of ceramic insulation and embossed stainless steel foil. Unlike wraps or coatings that degrade quickly, Redstar shielding delivers long-term durability and consistent protection for engine bay components.
