RE: BMW M135i: Spotted

Weird, I have M Performance exhaust and no drone at motorway speeds!


It defo needs a diff. I tend to drive it pretty chilled on the road and have my fun on track, it's a hoot there!

Doesn't quite have the get up and go of a hot hatch but it's a different.

Wonder how much of the drone some people report on the MPE is actually from the symposer?

It happened in all modes so with and without symposer. And it wasn't in your face but was audible enough to annoy (some might not be bothered by it depends how sensitive one is to certain frequencies and harmonics) and it didn't happen with standard exhaust. I usually had to sit in 7th gear which was just outside of the "drone zone". Unless I was on a German autobahn obviously
