Thanks Dave. You and me both!!!

The cats are OEM Holden/HSV cats from my 2013 HSV R8 - obviously modified to fit. When the car was 2000km old, I put a full Walkinshaw system on my car incl high flow cats so I had these left over. They're basically brand new.

The fabricator (Andy) is ex-HSV and he called HSV a couple of weeks ago to speak with a former colleague who told him they tested a number of cats when they were developing the GTS and the only cats that would pass the IM240 test were these ones. So basically, all Holden/HSV VE/VF V8's, both NA and supercharged are running these cats. They're 400 cell items so I wonder how much extra power would be liberated if 200 cell cats ever found their way onto the car?!

Sounds like an excellent resource to have.

Just to check I am understanding this. The Cats you have fitted on your PACE 427 are what HSV use to get their engines to pass Euro 5 emissions standard.

Australia wide for registration we only need to meet ADR 37/01 emissions level which is an old USA emissions level that was used before Euro emissions. So ADR 37/01 is actually about 5 levels of emissions older than Euro 5. So significantly less stringent requirement when it comes to emissions levels.

So by fitting the factory Cats it should give you extremely good emissions result.

IM240 is the type of test, not level. I expect you know that, it is read like it wasn't for anyone else reading that is new to emissions.

Hi Craig，

Yes, I believe that HSV and Holden are using these very cats on the VF models to pass the current Euro 5 emissions.

And yes，the IM240 is a type of test. From what I understand you either pass it or fail it and you get one go. Retests incur a new $800 (roughly) testing fee. Every VIC and NSW ICV that is going for full rego has to take and pass this test. In Victoria，Vipac are the only ones who can administer the test.
