Akrapovic Mercedes-Benz W177 C118 X118 OPF GPF Catalytic Downpipe (A 45 & CLA 45)

Part No. DP-ME/SS/3

Pre-Order or Notify me when back in stock


The Downpipe with Cat (SS) was tested and developed together with the Evolution Line (Titanium) exhaust system and offers an ideal upgrade to the Evolution Line (Titanium) system for further tuning. This addition is primarily designed for track use and will create a pure racing sound for the engine. Equipped with a high-flow 200 CPSI sport catalytic converter, the downpipe eliminates the OPF for a completely different sensory experience the moment the driver’s foot comes down! The sound level is noticeably increased and accompanied by a deep and powerful tone in the low and mid rev ranges, developing into a pure race-derived acoustic delight in high revs, which the occupants simply won’t get enough of! Every gear shift is full of crackling sounds, and the exhilarating tone is accompanied by an addictive burbling on every over-run in the sportiest settings. Despite being a track-oriented system, it retains all the comfort when you want it in Comfort mode, with no unwanted sounds or drone in the cabin.

When installing the Akrapovič Downpipe with Cat, remapping the ECU is mandatory to prevent potential “check engine light” warning signals.

Please Note: This product is available for 2021 vehicles equipped with an Otto/gasoline particulate filter (OPF GPF). Two additional EGT sensors have been added to the existing Downpipe to make it fit on Mercedes-AMG A 45 / CLA 45 model year 2021 equipped with OPF/GPF.
