catalic converter

[R33S2]

My car without cat passes all current emissions tests, and so is perfectly legal in Britain.

So you are saying that cats are not required in pomgolia? Or is it that they cant test emissions for waste products that cats remove? The cat is there for a reason no matter what reason that is they impose a heavy fine for tampering/removing them, why is that so Dr Clark?

put a 3" cat on, then put a 3" straight pipe on the car.

do dyno runs as close as you can

you'll be surprised at the difference

Its going to depend on the brand/model of cat. SydneyKid has provided some good solid evidence that a cat -- namely the 4" magic -- doesn't have to mean sacrifices in power.

The Apexi 3" is meant to be very good too, but I haven't seen anyone with solid figures.

lol,Lets all convert to LPG. 100+RON

Vapour Injection systems with twin convertors to handle up to 400kw @ the flywheel. Youd be lucky to get change out of $4000

Huge reduction in emissons.

The Vapour Injection unlike the traditional gas carb or suck through O-ring returns the same fuel economy figures as petrol, just at half the price.

Put a 4" cat on and compare to a 3" straight through pipe and you won't see any difference. I have and it's true, other people have and found the same thing, Zoom did it and agreed and printed the results.

In my opinion the loss of power excuse is out of date.

You used to be able to rely on LPG for 100 RON, but since they started to make it to a price, not a standard, I personally can't depend on it any more. I have a friend with a Cobra replcia that runs on gas and he is having more and more problems with pinging. Very few people buy LPG for its RON, they buy it for it's price.

Hey SK,

How do the new range of stainless steel (inside) 3" cats that BATMBL has for sale compare to the Magic cats? Is it worth putting a 4" cat on the GTiR, like would the GTiR be pushing enough power to make it worthwhile?

Thats the ones he's got for sale - although I'm unsure whether the actual cat is 3" or 4".

*Thought I'd drag up an old thread instead of starting a new one.. I know how to use the search button *

My car was registered without a cat but I'm sick of the stink every morning and when sitting at the lights sometimes you can smell it... I've quit smoking so I live longer, and would hate to be poisoned by something so minor.

Anyone know if these Magic cats are available in WA or recommend any other brands to source?

Thanks

rev ur car few times, im saying like 5-7k styles, if u got water spraying out of ur exhaust..then you got complete combustion. As ive been told that means, fuel is being combusted 100%. Then resort to straight cat, shouldnt be any problems with emissions if that is the case.

A 3" hi flow cat would be a good upgrade to finish off the exhaust, and create a lot less restriction, you will definitely feel the power. A straight pipe will have no restriction and you feel a lot more power compared to hi flow cat.

One of the catalytic converter's biggest shortcomings is that it only works at a fairly high temperature. When you start your car cold, the catalytic converter does almost nothing to reduce the pollution in your exhaust. This is an important note when taking your car for a complience test - make sure that it has had a good steady run to heat up the Cats to working temperature or you could fail your emissions test.

anyway..u can de-cat ur car if u want...but if everyone did this the world would be a much shitter place...do ur kids a favor and buy a decent hi-flo as suggested and produce less pollution.

Yes but most of the time the exhaust gas is too hot to cool down and condense to water on an aftermarket system, so that theory is Not that water would be a signal for anything anyway lol

Thanks guys, I've done a bit of research and I've joined a GB for a MetalCat for $280 instead of $380
