Is it the standard exhaust or the upgrade M Performance one?
I tweaked my standard by bypassing the valve on the passenger side pipe. Was fed up of the right pipe getting sooted up, so bought the BMW bypass part and the valve is permanently open now. Adds a bit more of a throaty noise in Comfort.






Five min job. Let me know if you want the part number.
I fitted a blanking connector back into the valve to make sure it doesn’t get mucked up.

Just a standard exhaust with the carbon tips, so definitely needs more noise. Exhaust upgrades seem to be extortionate, starting at 2k upwards 🙄

Depends where you go. The Power and Sound upgrade from BMW is currently on offer at £1700. Cat back exhaust and an ECU tweak to give an extra 40 bhp. 500Nm if you have the auto box. And it’s warranty friendly!
