Transform the soundtrack and presence of your G22 M440i with a premium valved rear exhaust upgrade featuring quad 84 mm straight-cut outlets with carbon fibre inserts. This precision-made system retains factory flap control for seamless operation through your drive modes while delivering a deeper, more aggressive tone and reduced backpressure for improved response.
We have fitted this system on customer cars and the feedback has been outstanding. Expect a richer note in Sport while remaining civil in Comfort. The craftsmanship, fit and finish are exactly what you want from a high-end European exhaust upgrade.
Why choose this upgrade
- Deep, motorsport-inspired sound with valve control retained via the factory actuators
- Stainless steel construction with a shot-blasted finish for durability and a premium look
