My L99 now with SOLO Cats sounds rather odd when it goes OUT of 4 cyl mode. In 4cyl its quiet but as soon as any gas is added even to maintain speed it goes into 8 cyl mode and I hear a pop/growl from the car.

I used to feel a vibration when it went in/out of AFM but now mostly just the growl when it comes out. Still no real decel popping unless in manual mode.
