Re: How to get certification for exhaust?
yogi, out of curiosity, y r u interested in getting the cert?
if it's for inspection purposes, suggest that you find out where the original owner got his exos installed, and get the same workshop to send your car in for inspection. should be much more convenient that way.
otherwise you have to get the schematics from the manufacturer and send them to LTA for approval. plus you are not supposed to use the exos until it is approved.
u will then be at the mercy of a pencil pusher - wait till he/she feels like it before they look at your request.
a case of inviting unwanted attention if you ask me...
