Mercedes-Benz A45 AMG Catless Downpipe — M133 2.0L Turbo

YPG Motorsport catless downpipe for the Mercedes-AMG A45 (W176) replaces the restrictive factory catalytic converter on the M133 2.0L turbocharged four-cylinder with a mandrel-bent stainless steel pipe. The M133 was the most powerful series-production four-cylinder in the world when it launched — and with the cat removed, the turbo spools faster, throttle response sharpens, and the exhaust note gains a deeper, more aggressive character.

When paired with a Stage 2 ECU calibration, the A45 delivers 420–440 HP and 380–400 lb-ft of torque from the facelift model (381 HP stock). The pre-facelift (360 HP) reaches 400–420 HP. For Stage 3+ builds with turbo upgrades, the downpipe is a mandatory prerequisite — it's the biggest restriction in the factory exhaust path.
