Relaxation of requirement:
This requirement has been relaxed to some extent, and now [within the latest version of LVV Standard
90‐10(01)] requires for catalytic converters to be fitted to only those production vehicles that undergo an
engine swap, if the vehicle was manufactured after 1990, and the vehicle was first registered in New
Zealand after 1 May 2012
Good news for me as i now dont need a Cat as i need to get a cert soon and it saves me $$$ and time! Yahoo!

so that is 89 and 90 MX5's that don't need the Cat for the cert. Mine is a NZ new 90 and the motor is an 04. Am fixing up a couple of things for the cert process, and a Cat isn't one of them.

I hope people arent serious about buying an 89 shell and swapping parts in just to avoid getting cat for cert... Just spend the $$$ and get hi flow cat... Cheaper than a registered 89 shell!!!

Just a word of warning, when I did my full exhaust I did not put a cat in. The only problem is it makes the car "smelly" for want of a better word. I dont mind but the wife always comments on it when the top is down.....maybe I just need to turn the stereo up so I cant hear her?

So basically... No matter what car you have if you give it side exhausts you don't need a cat
