Hey guys,

just wondering if anybody knows nsw road rules, but I recently got a new single turbo fitted to my 34GTR and i noticed that my car now has screemer pipes.

How illegal are they? and does anyone know how much the fine/defect is for getting caught? I like the sound they make but id rather not get a massive fine either.

Well I don't KNOW but I would assume it would be in te same category as no cat which I think is $5500 fine.... As screamers completely bypass all emissions hardware..... You sure it's not a split dump seems odd tht someone would install a screamer without at least letting you know ?!

Yeah im not too sure, it has 2 wastegates because its a twin scroll setup, but comming straight off the wastegates is two pipes about 40cm long that cutoff just under the engine..

Nice, i'd love to hear this thing on gate, it would be epic i'm sure.

Your in NSW, the worst state for EPA. Dont you guys have portable EPA detectors that sit on the side of the road, analyse the exhaust gas of your car, take a photo if its not correct and send you a nasty fine. Kind of like a speed camera? I've heard this before from several people.

Anyway, its quite a big no no, massive fines for it, attracts stacks of attention.

However, i'm one that is all for a screamer :)

First i have heard of these EPA detectors ? cant see how it would work, a police officer can report your car and it can be issued an attendance the EPA station that was the only way i knew of it happening?

I've heard of the road side epa, but I think it was only a trial.

And I'm pretty sure mainly aimed at trucks.

As for my opinion, not the biggest fan of screamers, give me a nice quiet exhaust any day.

I prefer the sound of the turbos on spool.....

Guys those sniffer cameras are no joke. Seriously. Fart near one and you'll get an infringement in the mail.

Fkn seriously where do the idiots that believe this shit get their info from?

Facts are these; a screamer pipe is not legal in NSW. The entire car can be engineered but not ever a screamer pipe. Any policeman with a basic understanding of how an exhaust works in relation to turbo waste will know what to look for. For the fine either ring NSW Police force HWP, RTA or check RTA online they may have it.

Lol. Never heard of those "super exhaust sniffers".

Yes when i heard it the first time, i called bulls**t very quickly and didn't believe it, then i heard it from two other people. But still didn't understand how they could get it to work. Well you guys live in NSW so you'd know the deal. I just know that NSW rapes their drivers more than they do over here in SA.

It's entirely possible to implement roadside gas analysis. It works on infra-red absorption by the gas species that they are interested in. They just shine an infra-red beam across the area they want to monitor and if any gases of interest are present in the intervening air at levels above some level of interest, then the light will be absorbed at certain frequencies, leaving a lower transmission amount of those frequencies that can be compared against the intensity of some other frequency (to use as a baseline). A big enough dip in intensity triggers the alarm, summons to the EPA gets sent. It's not possible to make such a system accurate or precise enough to declare that the levels of CO or NOx or HC are at any given numerical level, and certainly not precise enough to make the detection limit equal to the actual legal limt. So they just set them up to detect really high levels to avoid false positives. The intention was really only to catch the absolute clunkers and those vehicles that had been stupidly modified (which probably accounts for a reasonable percentage of our cars if you interpret stupid them way that the EPA/cops would). I don't know if they are still using them anywhere, but they certainly trialled them here in SA for a while a couple of years ago. Ultimately, it's a lot of trouble to go to to catch a very small number of rotten cars and trucks.

How illegal is something illegal?

Didn't realise there was a "scale" of such things :closedeyes:

People measure it in how much it will cost them :P

So in the worst case scenario, have a screamer pipe is Verrrrrrry illegal lol.

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
