Anyway, has anyone tried to tackle this and had any success in reducing it without harming the soundtrack from the engine?
And at a slight tangent, now that many owners have models with a few miles on the clock, have there been any other NVH issues that have surfaced?

THe booming noise was designed out with the standard quads, the X-power put it back big time. I had the use of a car with them on for about two weeks and it became too much. Loved narrow lanes with the windows down though
I have Zero Quads on now and they are about half way between the two and produce a lovely rumble sound.
