Just checking with you guys here if the installation of aftermarket exhaust system of 2 different makes and models illegal? When I sent my car for inspection last saturday at vicom yishun, the inspector failed my exhaust system despite showing the certificates. He explained that my car was fitted with a hks gt extension and a trust exhaust and silencer. When he scrutinised the certificates, he told me that only the hks gt extension was approved since it was the lastest add-on and it supersede the installation of the latter which was fitted to my ride at an earlier date than the hks.
