good link by the way, i think i saw them before on ebay
if porsche thought it needed this i am sure they would have done it though, i cant really see the point. I find the boxster very quite infact people always comment how quite it is when i give them a lift.
each to his own though, each to his.
boxster turbo, i like it:
