Unlock the full performance potential of your S63 AMG with our Gapped Industries Catless Race Downpipes for the W222 4.0L M177.2. Designed for enthusiasts seeking maximum power, sharper throttle response, and an aggressive exhaust note, these race-spec downpipes significantly reduce turbo backpressure and increase flow through the exhaust.
Engineered specifically for the M177-equipped S63, these downpipes feature a full 3” diameter design to promote unrestricted airflow from the turbos, enhancing both horsepower and torque output.
Crafted from high-grade 304 stainless steel with TIG-welded joints and 1.5mm wall thickness, they provide a resonant, deep exhaust tone while offering superior heat resistance and structural integrity.
Gains of up to 167–182 HP and 201–238 TQ at the crank when paired with ECU/TCU remapping from our select tuning partners.
Built from TIG-welded 304-grade stainless steel for strength and long-term durability.
Holes for O2 Sensors are built into pipes to avoid CEL.
Direct fit for 2018–2020 S63 AMG (W222) – no cutting, welding, or modifications needed.
Includes all necessary nuts, bolts, and clamps for installation.
60-day return policy for issues related to fitment or manufacturing defects.
