Is A Cat Really Needed?

[BrynDETT]

up here in qld they dont seem to care very much about cats..

twice i have been fined for being to low, and on the one occasion where i got on my knees to see what he was talking about the cop was poking my decat pipe with his little height wheel thing.. never said a word..

mine is a 3" stainless decat, doesnt even look like a cat haha

As of 5 weeks ago, high flow cats are LEGAL in NSW. As long as the emissions are still met lol

I had a cat on my r33... but my PFCpro has launch controll.... bits of cat come out the exzaust lol decat without removing it

It's amazing the stuff that comes out of the inside of the cat.Bout a quarter of a bucket full.

This is why it's important to get a cat with metal substrate.

I have never in my entire life heard of someone other than a trucking company get one of those $10,000 fines, and that was only because they regularly hadn't met the service time frames for the cat/muffler/particulate filters.

I haven't even heard of a workshop getting fined, not even forum heresay let alone proof.

its the max penalty

I just don't see the point of running a decat. The difference between a decat and a good quality high-flow cat is negligible, you wouldn't even notice it. You can get a good metal high-flow for so cheap these days, it's bordering on irresponsible to run a decat simply for the sake of $50 or $60. Why even debate whether you should use one or not?

The difference is more than $60, if you want one that's going to flow 250rwkw and higher. Also, flames are rad

I paid $160 delivered for my 5" body Venom cat (though after a quick search on eBay, I notice prices have gone up), am currently making 260rwkw with no restriction from the exhaust. Will soon be pushing 300rwkw+, will let you know how it goes then but I highly doubt it will be a problem. Considering I was quoted $100 to have a decat pipe made up (there was a stage when I thought my cat was a restriction where I considered going decat, but it turned out to not be the case), there isn't THAT much difference in price, and it's certainly not enough of a margin to tempt me to run a decat at all.

Flames are pretty rad though
