Scorpion De-Cat Downpipe - Toyota GR Supra (A90) 3.0 / BMW M240i (G42) / M340i (G20) / M440i (G22) / Z4 M40i (G29) - 125mm
Scorpion's rest-of-world (non-GPF) de-cat downpipe fits the B58-powered Toyota GR Supra (A90) 3.0 and the BMW M240i (G42), M340i (G20), M440i (G22) and Z4 M40i (G29). The large 125mm (5") T304 stainless pipe replaces the factory downpipe and catalyst, cutting back-pressure for quicker spool and a deeper, louder note.
Note: Non-GPF version. Australian-delivered GR Supras and BMWs have no GPF, so this is the matching version (Scorpion's GPF version is STYC011). 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.

- 125mm (5") T304 stainless steel pipework
- De-cat design – no catalytic converter
