i didnt relise they were failing cars on noise lever till weds in the test centre, i seen it on the wall chart max 99dbh aloud, i was sure he was gonna fail it cause my car has a zegin cat back exhaust and its fairly loud to say the least :oops: even people in the waitin room were commenting on how load it was and how much he was reving the car!! :x he held it at 3000rpm for a solid 4minutes i was sure he was gonna fail it, but it passed no problem :D :D i was that suprised i asked him and he said its on the testers discretion to check it for noise level i think i got very lucky, sorry to hear you geting trouble noting worse than when they fail the car on stupid things :evil:
