Mercedes-Benz W205 C43 Catless Downpipes — M276 3.0L BiTurbo V6

YPG Motorsport catless downpipes for the Mercedes-AMG C43 (W205, 2018+) replace the restrictive factory catalytic converters on the M276 3.0L BiTurbo V6 with mandrel-bent stainless steel pipes. The M276 responds extremely well to exhaust modifications — the factory cats are the single biggest flow restriction in the system, and removing them delivers immediate gains in turbo spool, throttle response, and exhaust note.

When paired with a Stage 2 ECU calibration, the C43 delivers 440–480 HP and 450–480 lb-ft of torque — enough to trade punches with a stock C63 S in straight-line performance at a significantly lower purchase price. For 2019+ models, a CPC (Central Powertrain Controller) flash is required alongside the ECU tune to unlock full power.
