Transform your Mercedes S560 and S560 Maybach with Redstar performance exhaust downpipes engineered for the M176 4.0 twin-turbo V8. Precisely matched to the 2017-2020 W222 Sedan, C217 Coupe, and A217 Cabriolet, you can choose Competition catless, GESI GEN2 400cpsi, or HJS HD 200cpsi configurations. Any version can be specified with Redstar OEM-style integrated heat shielding to cut radiant exhaust heat by up to 80%.

Replacing the factory downpipes unleashes markedly improved gas flow for sharper throttle response, faster turbo spool, stronger power delivery, and a richer, more engaging exhaust note. Enhanced thermal control contributes to lower underbonnet temperatures and supports long-term turbocharger durability for demanding driving.

Built for performance and longevity, every Redstar downpipe is 100 percent TIG welded and back purged using 2.0mm wall 304 stainless steel, with OEM-spec flanges and factory-style brackets for a true bolt-on fit. Motorsport-inspired thermal management and meticulous fabrication make Redstar the performance exhaust upgrade of choice for Mercedes S560 owners seeking a proven, high quality downpipes solution.
