When I hit 2500 RPM on my 3.0 (around 70 MPH) the "growl" of the exhaust gets louder and the steering wheel/gas pedal have a slight vibration to them. It's loud enough to notice the difference -- quieter and smooth at 2000 RPM.

Is this normal? I had been driving a 328i loaner for a week while my fuel pump was being replaced and I notice the noise/vibration even more now.

My X is going back in, they fixed the fuel pump but now the fuel gauge isn't working right.
