Hi,

I recently got my R34 25GT Coupe and want to change the exhaust so I can make it louder but not too loud so it sounds off putting.

I'm a P Plater in Victoria, I hear I can only change the rear piping after the cat for it to be legal.

I'm not too sure what to look for exactly, been looking around for days with little luck, so can someone please point me in the right direction?

Thanks,

Jesse

You won't get too far modding an N/A. If I only had a year and a half left, I would have bought a $1000 VT for the time being, and then bought a GTT.

Awesome. How much all up - $550? It's the first mod I did on my N/A back in the day. Very handy passing cops, going through RBT's, driving inlaws, being taxi boyfriend, talking, etc. With mine, addin

Being on p plates is just frustrating kind of a waste of money hahaha in the sense that you're going to upgrade when off p's

Hi, and welcome to SAU, the best place in the world for all things Skyline.

According to the Victorian "P" Plate laws, any vehicle (Even Mum's Camry) can be considered prohibited if it: "has an engine that has been modified to increase the vehicle's performance (other than a modification made by the manufacturer in the course of the manufacture of the vehicle"

This means that exhaust mods are basically off the table for P Platers, as even a cat back, like you mentioned could theoretically give performance gains. Still, many do it anyway. (A cat-back on an N/A would give very small, even possibly non-existent gains)

If you still want to do this, try to be a bit stealthy about it. (An R34 with P Plates on it is already a cop magnet, regardless of modification level)

I personally suggest ringing up or emailing your local exhaust shop, and getting a quote for something made up and installed, as most popular brand made bolt on systems systems are for the GTT (Turbocharged) model.

Completely avoid the cannon, and try to stick to the stock twin tip look, to avoid attention from anyone unwanted.

Maybe look into getting an X-Force Varex muffler, which allows the volume to be controlled if you want to keep quiet if need be, to avoid unwanted attention.

The RB25 sound can actually be quite nice, if done properly.

Good luck with your R34.

Thanks Burger, I'll have a look.

To get a good sound, do you reckon I should look out for a muffler with a 2.5" inlet and a 3" outlet?

I found a single tip and double tip that look alright but not entirely sure what I should look for when referring to sizing.

With mine, adding a pod makes a difference to the exhaust sound. better inhale = better exhale. or maybe a high flow filter will work on your airbox. I never tried it though.

Both is illegal here in NSW too. I got away with it for 3 years and I got defected for Pod filter. They said nothing about the exhaust. Now using the airbox since that day and my GF driving it now.

Just don't spend anything else until you get turbo skyline, you'll need the money, trust me! been there done that! :P

Goood luck

Yeah it was around 700 really, paid a bit extra to get it done properly considering I went to a few places that said they couldn't do the job.

I'd love the turbo but I'm not sure if I'd be able to make the extra money for when I get off my p plates.

Would love a garage too, less likely to be keyed!

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
