Hi all,

Don't know if i'm posting in the right area.

I've got a 4 door 1998 GT R34, i've had to fix a few things but the next thing needs fixing is the exhaust. Rusted so needs replacing.

Now i see if im replacing it i might as well put something good in there instead of stock.

Now i need some help on where i should be looking and what im looking for (completely dont know.. brother in law does insteas)

I've heard that P platers have a certain restriction on what can be put on the car as it counts as a performance upgrade and theres a limit to what the car can do.

So i'm looking for a cannon to be put on the car but i don't want just a tip i want it to be right so if anyone can give me some suggestions of what i should be looking for to make it still legal for p plater to drive i'd appreciate it.

In Sydney by the way.

Cheers

Put in a straight through 4" Inch exhaust, no cat, biggest cannon you can find and it will sound tuff and will be legal : :thumbsup:

Or if you dont wana hear anymore sarcastic responses lyk that use the search button..

Seems lyk the NA section is just covered with topics about exhausts... GAHHH

Yeah tried searching through a bit but couldnt find anything about being legal for p plater etc and to do with same skyline as mine so wanted to see what ppl would say. Thanks for that

its not an engine modification so all the rules that apply to every other driver will apply to you as well when it comes to exhausts.

i.e it must not go over 89 or 90 DB loud.. not sure check with EPA

everyone suggests 2.5 inch mandrel bent for a NA skyline, just get an exhaust shop to weld you a 2.5 inch cat-back pipe to a canon and bobs ur uncle. it will cost ya around $300

u didn't find anything about it being p-plate legal for a car caus it doesnt exist.

welcome to SAU, before posting a question next time, search the forums or GOOGLE it.. ta

I would 'think' that the 'legal' option is to replace it with a replacement OEM exhaust. Of course this isn't always the practical alternative.

Replacing with say a turbo factory exhaust will give you the flow and performance without all the added noise and unwanted attention.

Alternatively, do a custom 2.5" exhaust, but make sure the rear muffler at least "looks" factory, and you use enough resonators to quieten it down, and you will have a good flowing exhaust that won't attract too much attention, and at least you could try and justify that you replaced a rusted exhaust with something that was close enough to factory.

It seems that some cops will pull up any p plate skyline to inspect for illegal modifications; others probably won't harrass you about the exhaust.

The bottom line though is that any modification that affects the performance of a vehicle is illegal under a restricted provisional licence, and try justifying a performance exhaust on a skyline to a police officer who would expect the story to be made up.

I was under the impression that a performance exhaust is still illegal? If I'm wrong I stand corrected. As usual the RTA laws aren't exactly clear cut in black and white when it comes to what can and can't be done.

Those two threads sum up most of the discussion that's been had here on N/A P Plate Performance which will probably answer other questions you may have.

however if you are concerned with the legalities of modifications - isn't the most logical place your local transport authority? it varies from state to state, so there's no real point asking here; what might be ok for one of the guys here may not be ok for you. so whatever you read on the forums i suggest that you do a bit of your own homework and pick up the phone to whichever legal transport authority it is in your state.

N-dawg put up some good threads, have a look around the forum and see what else you may have missed.

If you want an exhaust, here's some threads to get you started. Please ask any further questions in those threads.

      Need AC Compressor for R32

      By R3N3 · Posted

      Haha im flattered! Although my poor boat is collecting dust in the garage, as it hasn’t been driven in like 6 months. I forgot the to put the trickle charger on too, so the battery is likely toast now.. I have the frenchys kit. It is fantastic. My only gripe was that the hard lines from the firewall needed some tweaking, however, this was mainly due to my specific turbo and dump combo. The weight and size packaging is much nicer too. I think I have some pics on my build thread somewhere.. my justification for the kit was more “why not” I had gone to the trouble to modernise just about every other part of the car..

      Does 98ron contain ethanol?

      By GTSBoy · Posted

      Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol. With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.

      Will I Need A Retune After Cahanging My Catalytic Converter ?

      By Murray_Calavera · Posted

      Maybe? If changing the cat to a higher flowing cat, caused the turbo to spool more quickly, and those areas of the map had not been tuned for the boost level it is now seeing, then yes you would need a re-tune. How dangerous it is running without the updated tune would depend on how far out the tune is with the now higher boost levels, how the engine protection has been setup, is the ECU compensating with a wideband sensor, is the boost control closed loop blah blah million other things... But yeah having said that, I wouldn't be surprised if changing out the cat for a high flow, in say a full 3" exhaust, made no noticeable difference at all.

      Need AC Compressor for R32

      By silviaz · Posted

      Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.
