NVH - curing the boom
If there has been a comment I have heard a few times from owners or passengers in a 260, it's the boom the car creates at around 50 - 60. The last time I was in one it had the XPower pipes on and it did give quite a medium level noise that was a bit intrusive really. I seem to remember that Project Drive removed quite a bit of sound deadening although I'm not sure if that applied to the ZT in some respects.
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?
