Scorpion De-Cat Downpipes - BMW X3 M (F97) / X4 M (F98) incl Competition - 89.9mm
These Scorpion de-cat downpipes replace the factory downpipes and catalysts on the pre-LCI BMW X3 M (F97) and X4 M (F98), including Competition models. The 89.9mm (3.5") T304 stainless pipes reduce back-pressure on the S58 twin turbos for sharper response and a louder note.
Note: Pre-LCI (2019-2021) models only. Australian-delivered BMWs have no GPF. 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.
