BMW M440i (G22) (22>) (UK/EU) Valved GPF/PPF Back to OEM tailpipes Performance Exhaust

Unlock the soundtrack your 4 Series deserves with a premium valve‑controlled sports system designed specifically for the M440i G22 Coupe (2022 onward, UK/EU). This PPF‑back setup runs from the petrol particulate filter to the tail, replaces the centre and rear sections and keeps your factory finishers for a stealth OEM look with a serious sound upgrade.

Crafted in high‑grade 3 inch, 76.2 mm stainless pipework and finished with a single valve and race rear silencer, this system delivers a deeper, richer straight‑six tone from the B58 while preserving everyday usability. Expect a noticeable increase in volume and character in every driving mode, with sharper throttle response feel and a properly sporty note when you want it.

We’ve fitted this system on customer cars at MJ Modifications and the feedback has been outstanding – crisper start‑up, stronger mid‑range presence and zero fuss on fitment. It’s the ideal exhaust upgrade for drivers who want maximum sound quality while retaining the subtle, factory rear styling.
