Mercedes-Benz ML63 Catless Downpipes — M157 5.5L Twin-Turbo V8
YPG Motorsport catless downpipes for the Mercedes-AMG ML63 (W166, 2012–2017) replace the factory catalytic converters on the M157 5.5L twin-turbo V8 with mandrel-bent stainless steel pipes. The ML63 shares its powertrain with the E63 S and G63 — the same proven M157 that responds aggressively to exhaust modifications.
Removing the factory cats delivers faster turbo spool, reduced exhaust gas temperatures, sharper throttle response, and a deeper, more aggressive AMG V8 exhaust note. When paired with a Stage 2 ECU calibration, power gains are substantial — the M157 has enormous headroom beyond its factory 550 HP rating.
