knocking noise
Having fitted the Cargraphic exhaust I have noticed a knocking sound when accelerating. Its not very loud but I can definately hear it. When I accelerate hard there is no noise but otherwise its very obvious. I asked Porsche and they felt it was road noise from the back tyres - the engineer came in the car with me. Does anybody have any other theories?
