Bought my 1st BMW 2 months ago and so far so good, 2018 440i with 7k miles so as good as new.
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.
Just a standard exhaust with the carbon tips, so definitely needs more noise. Exhaust upgrades seem to be extortionate, starting at 2k upwards 🙄
