Scorpion De-Cat Downpipe - Mercedes-AMG A45 (W176) / CLA 45 (C117) - 89.9mm
This Scorpion de-cat downpipe replaces the factory downpipe and catalyst on the Mercedes-AMG A45 (W176) and CLA 45 (C117). The 89.9mm (3.5") T304 stainless pipe reduces back-pressure on the M133 for sharper turbo response and a louder note, and it connects to the OE exhaust or a Scorpion system.
Note: Pre-GPF generation. Scorpion states this part removes a factory emissions control device and is for motorsport use only. Expect the engine management light to come on; Scorpion recommends a Stage 2 ECU remap. Installation by a professional is recommended.

- 89.9mm (3.5") T304 stainless steel pipework
