What exhaust system do you have? I passed with a HKS Hi Power silent...and I put the stock air box on to lower the volume.
Check that you have a rear eye level brake light as well, since you've got a GTR rear wing.
And anothet thing the inspector told me to bring next time was a certificate of Exemption if you'r car was imported under the 15 yr old law or you don't have a Compliance plate.
BTW a cop was following me last night at around 1am and probably was going to pull me over. Luckily by the time he was in view I was home, so he just drove past slowly and just gave me the look
