I personally wouldn't run any cats unless they are design for a FI application. A good option would be GESI. They have a high HP & EGT rating (1500f). These are run on ams/ets gtr exhaust systems. the only downside is the price and they have to be cut and welded in to your exhaust.

After I took the BP kit off I swapped to Berk HFC's when I was NA for about 2 months. Then I swapped to the Motordyne ARTS after I installed my supercharger and they sounded exaclty the same as the catted berks. Only I didnt have to worry about plugging them up and ruining them, and possibly my engine. Not to mention the added few HP/TQ.

If I ever did it again, it would be ARTS all day every time. Granted i was on E85 so the smell wasn't an issue.

Resonated TP and Mil Spec cats. Call Tony or Kevin and they will set you up. Just be prepared for the wait.

Their workmanship and quality is well worth the wait on FI products.

I will need cats soon for emissions purposes here in Australia.

I was recommended the Gesi cats by a reputable tuner, but is the double price tag worth it over something like the mil.spec cats?

If you only need the Cats to past emissions there go with the mil spec cats at FI. They will get the job done! No sense in spending money on the Gesi cats for double the money unless you want that particular brand.....especially since you only need it to pass emissions.

Well actually, I don't need to pass emission yet as my car hasn't been flagged yet. But when it does, if it ever does get flagged by the police I will have to go through the pits and pass the emissions test.

But before any of that, if I do get pulled over by a cop and they look underneath the car for an initial inspection, currently they won't see any cats as it is straight piped atm. And the fines over here for not having any cat converters is insanely huge. Im talking like $10K!

So I am thinking of gutting some standard cats and placing the shell over the pipe so it looks legal lol

And then if they still send me through the pits I will have to actually buy some cats and pass the emissions.
