Mercedes-Benz GLC63 Catless Downpipes — M177 4.0L Twin-Turbo V8

YPG Motorsport catless downpipes for the Mercedes-AMG GLC63 and GLC63 S (X253 / C253) replace the restrictive factory catalytic converters with mandrel-bent stainless steel pipes. The GLC63 shares the M177 4.0L twin-turbo V8 with the C63 and E63 — and the same tuning potential. Removing the factory cats is the single biggest bolt-on power gain available on this platform.

When paired with a Stage 2 ECU calibration, the GLC63 S delivers 650–700 HP and 700–750 lb-ft of torque — transforming the SUV into one of the fastest vehicles in its segment. The all-wheel-drive system hooks everything. For Stage 3 turbo builds targeting 850+ HP, downpipes are a mandatory prerequisite.
