Mercedes-Benz CLA45 AMG Catless Downpipe — M133 2.0L Turbo
YPG Motorsport catless downpipe for the Mercedes-AMG CLA45 replaces the restrictive factory catalytic converter on the M133 2.0L turbocharged four-cylinder with a mandrel-bent stainless steel pipe. The CLA45 shares its entire powertrain with the A45 — the same M133 engine, the same tuning potential, and the same modification path.
Removing the factory cat delivers faster turbo spool, sharper throttle response, and a more aggressive exhaust note. When paired with a Stage 2 ECU calibration, the CLA45 delivers 420–440 HP and 380–400 lb-ft of torque from the facelift model (381 HP stock). For builds targeting 500+ HP with the YPG Stage 4 turbo upgrade, the downpipe is mandatory.
