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.\u003c\/p\u003e\n\n\u003cp\u003eWhen paired with a Stage 2 ECU calibration, the A45 delivers \u003cstrong\u003e420–440 HP and 380–400 lb-ft of torque\u003c\/strong\u003e from the facelift model (381 HP stock). The pre-facelift (360 HP) reaches 400–420 HP.
