Mercedes GLC43 Catless Downpipes — M276 3.0L BiTurbo V6
YPG Motorsport catless downpipes for the Mercedes-AMG GLC43 (X253, 2018+) replace the restrictive factory catalytic converters on the M276 3.0L BiTurbo V6 with mandrel-bent stainless steel pipes. The GLC43 shares its powertrain with the C43 and E43 — the same proven M276 platform that responds aggressively to exhaust modifications.
Removing the factory cats delivers faster turbo spool, sharper throttle response, and a deeper exhaust note. When paired with a Stage 2 ECU calibration, the GLC43 delivers 440–480 HP and 450–480 lb-ft of torque. For 2019+ models, a CPC flash is mandatory alongside the ECU tune.
