OPF and muffler delete = drone

bbbbadfish · 10-19-2023, 12:33 PM

Picked up my 2020 330e from my exhaust guy today. I now have the exhaust going straight through from after the cat and ive got a terrible drone on cruising/highway speeds but christ its awesome and angry when driving regularly.

I went a bit all in gambling if I was gonna get this drone after reading this and that but yeah now im considering putting the muffler back on. Anyone else done the same and what was the solution?

Ive got a euro spec so there seems to be OPF and resonator combined in an oval shape, then theres no resonator after like there seems to be on US models.
