Unleash the voice and response of your 2023+ Mercedes S63 S E Performance W223 with the AMG M177 4.0 twin-turbo V8 using Redstar performance exhaust downpipes. These direct-replacement downpipes integrate with the factory system to free exhaust flow and reveal the authentic V8 character with distinctive burbles and crackles.

Reducing backpressure and improving gas velocity, Redstar downpipes deliver significant power gains, faster spool up and sharper throttle response, while helping to extend turbocharger life. Configure your system with high-flow catalytic converter options to suit your goals, including HJS 200cpsi or GESI GEN2 400cpsi, and add OEM-style heat shielding with a ceramic inner liner that cuts radiant heat by up to 80% for improved thermal control under the bonnet.

Built for demanding AMG applications, each assembly uses 2.0mm wall 304 stainless steel, is 100 percent TIG welded and back purged, and features OEM-spec flanges and factory-style brackets for a true bolt-on fit on both LHD and RHD vehicles. Precision construction and RedstarÕs motorsport-inspired thermal management deliver a durable, high-quality downpipes upgrade for your Mercedes-AMG S63 S E Performance W223.
