I'm well used to loud exhausts. Something similar to your 135i, mine had AR catted downpipes with a Corsa exhaust and the secondary cats taken out. It was loud, but a great sound.
This resonance type noise just within a 400 rpm window has me frowning and clenching my teeth and I either drive below it, or accelerate quickly through it. Otherwise the exhaust sounds fine and is ok.

I'll pay more attention and see if I can hear a hint of it as I drive.
