Although yes it is cheap power i do agree, however as stated before it is far more dangerous to the environment and your bank account if you get caught. Do you know what gasses are emmited from your exhaust when you have no cat converter? NOx and COx (Nitrogen Oxides and Carbon Oxides) are the main ones, some of which are extremely toxic. A cat coverter chages some of these deadly gases into safer less toxic gasses.

Carbon monoxide is an example of this.

IMO Dont do it, its not worth it really when you thing about it.

Beer Baron: I've heard of cars brought over from NZ that don't have the cat on them, in fact I know someone thats had their S2 imported from NZ and it had no cat on it, and he had to pay for a new cat to get a safety certificate and he wasn't made aware at the time of puchase that it didn't have one. I was just wondering why/if its legal over there or is it just some loophole.

Just a Q.

Cheers :D

ah well that is different. in most countries (australia included) cat conversters only became mandatory after a certain year ( i think in aus it's 1986). so that year ruling can differ in other countries (for example in the UK I think it's 1992 or something).

U cant be serious?

I hope he really is!

Besides the first person who will suffer the most from those toxic gasses will be the moronic driver himself... I get shit loads of exhaust gas from my car every time the turbo timer is running... I cant imagine how much shit Id breath if my cat converter wasnt there... :D

thanks for all the replies, was intending on putting a high flow cat anyway incase emissions were to be tested by my friends (police). Wasnt sure what cat actually did or what fines were. However you would be surprised how many people just ram a steel tube thru their cat to free flow it.

I hope he really is!

What about cars from pre mid eighties that dont have cat converters. my bro has a killer xy gt that ran on av gas b4 laws changed, he hasnt dropped dead from toxic fumes.

also if you ran a hose from your exhaust into your car window you would be dead within a minute, cant get anymore toxic than that with or without your cat.

What the cat converter does is uses a catalyst such as platnium or vanadium i think to convert the main toxic gasses (CO-Carbon Monoxide and NOx-Nitrogen Oxides and Hydrocarbons) into less harmful gasses. These are all pollutants which are both toxic and cause pollution known as smog. Even the hydrocarbons can be broken down by the sun into Ozone (O3) which attacks rubber, and cuases respiratory problems at ground level.

These less harmful gasses are CO2-Carbon Dioxide and Nitrogen gas (N2) plus some additional oxygen and some water vapour. All of which are far less detrimentral to the environment or anyone standing around yor exhuast.

So if you were to stand at your exhuast for an extended period of time with no cat, you would eventually just feel dizzy and or faint from reduced oxygen in your blood.

In the end, highflow cat is the way to go IMO.

How long have petrol cars existed? Notice how much damage in such short period of time cars have caused to the environment (ozone lair, global warming etc)...

People do something then they think why it caused problems...

Do I even need to mention atomic radiation and idiots watching it a few KMs away?

    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
