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

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

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.

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 :P

      Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy.

      The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.

      Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
