I think if you fail badly they don't give you any paperwork. The day I was there a guy with an imported RX7 was trying to pass (and he'd been there a few times already) but he didn't. He was running a JDM twin exhaust setup, but he'd had it modified, after failing previously, with two brand new cats and two mufflers on each pipe (total 4 mufflers) - he joked about not having any pipework just boxes connected to boxes. He got picked up in a random roadside Emissions test around Sans Souci (this was a few years back now.)

That's right!

That's what happened to me

Emissions Tech said its close to failing due to a cheap as x-force high flow cat and said I'lll leave ot up to your engineer..

My engineer said yup good enough for me
