Yes, quality OEM cats are highly recommended.

Due to our unique exhaust routing we can run the largest/bulkiest of oem cats very, very close to the exhaust headers without sacrificing ground clearance or creating heat issues. VE V8 Commodore cats are physically one of the largest around.

I'm still undecided if I'm going for full reg or club reg, so I may not even need to worry about cats.

But if I go full reg, depends on what the engineer says but I'll more than likely have to run an undercar system. It just so happens that I kept the 1200km old OEM cats off my E3 HSV when I put the 3" Walkinshaw system on. I also have a pair of brand new Outlaw 200cpi Euro III cats too that fit the Walkinshaw system. Which cats should I use?

Re the LSA fitment kit, yes, I'd be interested in that. I was sussing out the heat exchanger, reservoir and pump anyways but if you have a system worked out for the Pace 427 then I can definitely wait.

I'll be getting the engine controller kit from the states as my friend is coming in from St. Louis in March and will bring it with him.

I'd say the HSV cats have a better chance of passing the IM240 than a set of aftermarket "Euro III" cats.

According to the following info, Euro 4 came into effect for new passenger vehicles in 2008. There are special rules for ICVs but with Euro 5 and 6 being phased in, I wouldn't count on Euro 3 being acceptable for too much longer. Perhaps an engineer can chime in here?

Sambo, yes I am of the same belief, you can bank on the performance of OEM cats. Just keep in mind that not all OEM cats perform the same, it all depends on how "dirty" the original engine is compared to the emissions level they are trying to meet. kyleb mentioned he used XF Falcon cats for that reason.

EPA don't care what sort of rego you have when you are polluting. Besides no cats smells very bad.
