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.

      Rv37 400r questions

      By elir32 · Posted

      Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.   Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?     also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here.      also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system?    any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance

      Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel.  One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch.    These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height.    There is a lot going on in this picture and unless I did the job myself no way to tell what really happened.

      I did this mod in 2019  You just have to modify the top bracket of the ABS/TC/Fuel Pump Control ECU so it sits more upright and closer to the back seat and run a good quality positive battery lead from the engine bay, the negative lead i just bolted down to the body in the boot.
