A catback is better bang for your buck (costs about the same as a set of extractors, but is easier to install).

In an ideal world you'd do the entire exhaust system (extractors, cats, midpipes, rear muffler) for your gains.

The extractors on my car are nasty, but the catback still made a noticable increase in power. When I can, I'll probably replace the extractors and cats as well.

you can't put aftermarket extractors and leave the cat and exhaust alone... that's just a waste of time and effort.

However you can change the cat and exhaust and leave the extractors alone and still get some performance gains.

if that makes sense.

Would it be illegal if i modified my GTS with extractors? ( I'm on my P's and im in NSW)

Also could anyone point me in the right direction of finding a legal exhaust system? (size, manufacturer etc)

Appreciate it :D

local RTA is the only people that can answer that question 100%. Unless the extractors are all bling bling, you'll never get picked up on them by the cops anyways. You have a better chance of being picked up for a louder exhaust than aftermarket extractors, so make sure your exhaust is quiet (mufflers/resonators) and you should fly under the radar.

P platers aren't allowed to have any engine performance modifications. So even if the extractors only give 0.1kw they are considered illegal for a p plater.

As funkymonkey said, if they are fairly quiet cops probably won't notice them. However if they do notice them and decide to give you a fine, I believe you lose something like 7 demerit points for driving a prohibited car (as it is modified). This would mean loss of license for a p plater as you only have 4 points. You would have to get an absolute arsehole of a cop to give you this fine for just having extractors, but it is possible.

So IMO its not really worth the risk.

ok people I have the 1 million dollar question...

Where (on gods good earth) can you get a set of extractors (3") for a R33 GTS?

No one likes dealing with imports, let alone Skylines.

yep frustrating isnt it !!!

try COBY brand .

they are in NEW ZEALAND and do mail order . look in

www.partsco.com

price is au $ 287.53 plus freight

yeah coby extractors are good. i have them on my gts and you do feel the power gain. they do look stock. especially if you dont heat wrap them. the bright orange paint peals off like straight away haha

all i can say is it must suck to live in aussy :wacko:

NZ's got the mintest car laws. BOVs are legal, no cat needed, no real noise law, no power law thingy. its not perfect but its so much better then your laws

On the plus side, it keeps pre-literate idiots out of overpowered and undersuspended cars. From a government "oh won't somebody think of the children" perspective, that's a good thing. From a Darwinian perspective, its not so good.

The NSW laws say you can't do engine performance mods. Suspension, brakes, etc are still "free". So for those people that want to actually learn how to operate a vehicle in anything aside from accelerating in a forward direction only.

Hey guys

I just bought a 96 GTS-4 NA >_<

I want that unquie skyline sound of the stright 6. Is that possible or u need a turbo? I got a stock system atm...

Also if i install a Air intake kit will it make that deep inducion sound?

Kind Regards,

THai

atleast your car has a rb25de.. you dont need a turbo to get the stright 6 sound. turbos do give the awesome skyline sound but i dont think the cost of owning a turbo justifys it. gts-4 r33s are pretty rare from what i have seen. is yours manual or auto?

an intake kit will help your car make the good sound of a straight 6. ever thought of replacing the factory black pipe from the AFM to the throttle body with some metal pipe? your car will scream. larger exhaust piping plus some free flow mufflers will help you get that sound. or just chuck some coby resonators in there.

this is a link to a sound file that screamin'_skyline car that has a very simialr set up as what i discribed http://homepages.paradise.net.nz/jswright/screamin.html click on launch to see how it sounds when taking off

Hey BADR33,

Thanks for ya feedbak mate greatly appreciated!

Yeh theres only like 2 in adelaide i think i dunnoz?

Yeh i just bought the car yest n collecting it on 2moro.

My prob get air intake (kand N or Apexi) then an after market cat bk exhuast.

LOL its an auto..... :O but dats why i got it hell cheap...

Future plan is to do engine swap... but it still early days so i cintinue to do research.

What car u got bud?

mine is rb30de ( non turbo ) it has extractors and 2 1/4" exhaust system , with one muffler . the first intake i had was 3'' stainless pipe . now have 2 x throttle bodies and 2 pod filters . The sound is really really good . Its hard to describe brm brm noises , but when i run at the drags with the pipes undone at the extractors outlet flange , well the sound is one of the best car noises around

all good dude.

i have a 97 r33 gts manual 4dr with the mighty old rb20E!! haha.

im just starting work on my rb30de build. i could go turbo cus my rb30 block has the fittings there. but i love N/A and turbos are just becoming so commen and insurance is a killer.

i have a simialr set up to that car with the sound clip. just im using a factory rear muffler off a gts25t so i think my car is that great sounding from behind but the intake sound is what gets me all the looks ;) plus it looks bling as cus i used aluminum pipe and i polished it.

autos arnt that bad. my mate just put a rb20det in to his gts auto. and he says that he floors it and when it changes gear there is no turbo lag it just keeps pulling.

yeah keep researching. do searches on here and on www.skylinesdownunder.co.nz

on there you don't get shot down as bad as you do on here. lol

they let you do that? it doesn't get classed as too loud? also how do you mount the front pipes so they don't wobble round?

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
