Both E90 & E92 N51/N52 BMW PE systems include resonator delete midpipe in addition to the muffler

You cut off the stock exhaust about 6in back from 2ndary cats, and the PE midpipes clamp on - then PE muffler clamps to midpipe.

So they definitely mess with components under the front of the car, including the brace that runs under the midpipes toward the front

Components vibrating in the cabin is not drone, & is not normal after PE install. I have zero drone with PE on my 09 328iX & no vibration - installed it myself to ensure it was done correctly...
