Post Bmw 535ix exhaust drone

Hello everybody , i have a problem on my 535i bmw , i bought the car with an Magnaflow exhaust and the sound is amazing but sometimes on the highway at 120km/h at 2000Rpm i have a drone in car and some vibrations. I have soundeadending the trunk but on the highway sometimes its still annoying.

I put some photos with the exhaust and if you can tell me what kind of exhaust system i have on ? Straight pipe with just the mufflers ? Thankk you !!

i know that. I meant why would the previous owner do that? anyways, looks like he had all the resonators removed from the picture you provided. I would look into some vibrant resonators to quiet it down a bit. even than, you might have a slight drone but nothing like you're experiencing now

Have you looked into installing j-pipe? Seems like you have plenty room for it. Jpipe will bounce back the sound frequency and eliminate your drone. Should work
