I have a video of my exhaust if anyone wants to hear it.
Between 2.5k-3k RPM in 1,2,3 it droned straight to my brain, like at high speed when you have 1 window slightly down.

The Berk Full Race has high flow cats in the mids, and the catless dps dont cause drone.

So i would put it down to the lack of cats in the n55 mids.
