Catalytic converters? Needed for w.o.f?

[subrex]

Hey guys, have used the search and have'nt found an answer, also probably a newbie kinda question.

I'm looking at getting a new exhaust system for my wrx from the turbo back. But was wondering if catalytic converters were required to pass a w.of. I have seen many exhaust systems without them though recently read something that said it is a requirement?

Any help would be greatly appreciated

Cheers,

nope - but one day they might

I thought a couple years ago they passed legislation that a catalytic converter connot be removed from an exhaust system. So muffler shops had to chop your old cat into the new system.

Not too sure on whether it was actually passed i just remember getting a whole new system made for the Calibra before the July deadline.

hope not....

mines all straight through, as was my legacy.. both never got blinked at.. i think it got looked at but not passed

Wow that was really quick. Thanks alot, i just thought that i had better check with fellow club members before ending up with a headache and an empty wallet

As mentioned, nope.

However, one day we can safely assume that emissions testing at wof time will be the go.

Pretty much all new vehicles now are made to strict emissions standards and i would assume that in a few years time when these mid 2000s vehicles become "the norm" we will see this insiduously slide into the wof check.

You can buy a larger diameter cat to stop your original one choking your flow too much but unsure of costs. I just elected to ditch it altogether!

IIRC Keltik has the right idea... but you can only ask... but they are not a WOF fail item thats for sure

Decided to check up on it and found these lines in some LTSA reports.

"Comments are also being sought on proposed requirements

prohibiting the removal of, or tampering with, emissions control

equipment fitted in a vehicle."

I had a quick look but couldnt find out if that law actually got passed or just quietly dropped but im SURE in July 2007 they made it law as thats what prompted me to buy a whole new system before the deadline.

Either way if a muffler shop is willing to do the work for you, and it doesnt look obvious and rangi that youve chopped out the cats - i think youll be fine

Was looking at being passed along with tighter emission controls, however again too expensive for garages to setup the gear and along with for when cars require them ie New models etc... Been put into the too hard basket for now. Was meant to be in place by 07/08.... Well its 09 now and still nothing has happened lol

Also for the fact it's been proven the cats are completely useless after x amount of k's anyhow, which rules out a good majority of cars in NZ.

lol so we should all shooosh before it ends up on some ones radar again and we have to put on restrictive exhausts.

[Guest]

as far as i know they are still working on that emissions law

I just recently removed cat from my n/a legacy and it passed wof a week later no issues other than no rubber on clutch pedal and brakes lol

I have been told that if I don't get my cert by January 10, I WILL have to have factory cats inplace, but yeah info really seems to vary from place to place. This is just what my cert guy has told me.

Had a straight through stainless turbo back system on the wagon and that was never contested for over 2years

add another YAH for an oldskool Subaru they were released with out a cat(even though mine had one) which means it dont need one heheheheh

[subieboy]

I baught a aftermarket one to chuck in my system...

Full mandrel bent bliss turbos back... ;D

If any of you ARE 'planet conscious', and, yes, i am using that in a derogatory manner...

...and you DO have a catalytic converter fitted to your car (and almost no-one who does has ever changed it for a new one), then, you'd be doing the trees, fluffy bunnies and all the other creatures a HUGE favour by removing it and running a strait piece of pipe!

Cat's work for several thousand km's, and then they stop trapping harmful emissions and begin to disperse them...a compound similar to nerve gas (so i'm told).

So, save the planet, and run a straight through pipe!

Oh, and while i'm at it:

NO, the phenomenon known as 'Global Warming' is not describing humanity's heating of our environment; it is a natural cycle of the planets ecosphere.

The average mean temperature of our planet has been dropping since records began...(FACT!)

...and, by the way:

Those pesky CFC's that were banned from aerosol cans; Chlorofluorocarbons were blamed for destroying the Ozone layer, whereby Chlorofluorocarbons released free chlorine atoms which DO destroy Ozone. However, what the EXPERTS forgot to mention is that, naturally (and this HAS been going on for millions of years folks), the oceans give off billions and billions of tons of free chlorine atoms every year...

our donation to this? a few million tons a year...

yeah, it's us, no, really... :

You can't fool all of the people, all of the time, but, if you keep them dumb enough, you can fool most of them, most of the time...

Meh.

Mt Hutt keeps getting more snow every year recently so its all gd!!!
