Transform the 2020-2023 (facelift) Mercedes C63 AMG and C63S with Redstar Exhaust C63 W205 Facelift Downpipes, engineered for the M177 4.0 twin-turbo V8 across Coupe, Sedan, Convertible and Wagon. Designed as a direct replacement for the factory downpipes and built specifically for the facelift platform, these units incorporate the correct transmission brackets for perfect alignment and fit. Redstar is the sole manufacturer globally offering a facelift-specific downpipe solution, making this the definitive performance exhaust upgrade for your AMG.

Experience sharper throttle response, faster spool and significant real-world gains, paired with a deeper, more refined tone that delivers the aggressive burbles and crackles enthusiasts expect from a high-performance downpipe set. Optional OEM-style heat shielding reduces radiant heat by up to 80% to help manage under-bonnet temperatures and support turbo longevity during demanding use.

Crafted from 2.0mm wall 304 stainless steel for durability, this Redstar performance exhaust upgrade installs as a true bolt-on for the W205 facelift. Flexible configurations include HJS 200cpsi ultra high-performance catalytic converters, GESI GEN2 400cpsi converters or a competition catless setup. Precision engineering, motorsport-inspired thermal management and Redstar quality combine to optimise sound, response and reliability for your C63 and C63S downpipes.
