Akrapovič downpipe, manufacturer part number DP-ME/SS/3, for MERCEDES-AMG A45/A45S/CLA45/CLA45S.

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.
