Purchased a yahama R3 that came together with an Avropovic pipe from a dealer. Misplaced the cert for the exhaust pipe. Is the physical cert needed during inspection?

Hi Brendan, you require a certificate when going to inspection, if you've lost your cert you can try and apply for another one at LTA. More information at this link. https://onemotoring.lta.gov.sg/content/onemotoring/home/owning/modification.html
