haha, yes same, i was expecting a longer list of mods :thumbsup:

Pretty much as you said Steve.

Although i would just get 3.5" from the outset personally. Once day you might decide to get slightly bigger turbos etc and a tad larger exhaust could offer benefits.

Certainly no need for a 4" unless you are planning on a 400rwkw+ sorta build.

Also some merge's actually go to 3.5", i know the trust ones do... so certainly not all front pipes end up 3" @ the merge.

The trust ones do? The trust ones I had were 80mm, so I guess there must be a couple of different sets? They were all sorts of old though. I don't know the merge size on their new stuff

agreed on the 3.5" now but only if definatly going bigtime powerwise in the future ;)

Oh and something else Ash and I will agree on, got some money you just have to spend? Call RacePace for a custom exhaust. No one has done more RB development in Australia than them

My cat back is xforce. Yeah, huge suprise it hasn't been a restriction yet.

Tomei dumps. Hks front pipes.

As Ash said, list everything first

Interesting, it supports the theory that the exhaust is much more critical towards the front and less so at the rear.

Who's theory is that?

I'd argue it's equally as important the whole length. No point having a great front section if the back end is junk

Yeah actually, he spent 45 mins with the microtech the night before driving it to Victoria due to a faulty ecu another forum member sold me.

Yavuz wasn't happy with the tune but he said it's enough power for a weekend of fun but super safe so nothing will happen. On 98, 371rwkw 18psi. No mechanical changes the next tune was 403rwkw, maxed injectors changed to ID2000's and then tuned as is. Wait until my new exhaust is done, I'll be straight back to Yavuz for another tune with more boost etc

Edit; sorry, that was 3L. No one in Sydney ever tuned it while it was 2.6L, I misread your question, sorry. Also it's an 87mm bore, so a tad more than 260cc, but who cares it's splitting hair. Sorted out your pipes?

Ahh sweet. Do you know where Yavuz set the cams to? (thats if you have adjustable cam gears)

Re the pipes. I went to Westside exhuast on Friday. They quoted me $600. Went for a drive to Hypertune today and they said "a couple hundred". However they are in the middle of moving so they said to come back in a few weeks and they will have a better look. Just off first impressions I dare say i will get hypertune to do it.

No. 3.5" should do it. 4" if you want to be sure.

If I can make 455 with a barely 3" anyone can make 500 with a 3.5" IMO

+1 I make 330 with 3" dumps into 4 inch and am looking to make a tad under what N1GTR has without changing it.

if you can fit 4" it will save you from the "is my exhaust a restiction" dilema further down the road once the wick is turned up.

3.5 to 4" is not much cost differance either, 4" is more common in pipe size if you going to get one made.

Anyone know roughly what a 3.5" catback custom exhaust costs? Just a ballpark figure. I have a great exhaust setup from the turbo rear to a massive high-flow cat, but after the cat, it's shit (just reflanged to fit on to the cat until I can get something made up).

They're adjustable but set to zero still

you know if hypertune do it the welds will be perfect

im not looking for outright power at the momemen, i just want to highlite that charactaristic rb sound.

what will give me that? are dump pipes needed? do dump pipes change exhaust note?

some gtr's i hear are quiet, even with exhaust. some are too loud. i want a medium volume with that rb hum (if you know what i mean)

the car will stay standard at the moment, i just want a nice sounding exhaust.

    • The hot exhaust light will come on not from just the cat being blocked, but it's just a temp sensor, and it's designed to warn you to not do things like park in long grass.   If you've been pushing the motor a bit, it can cause the light to come on.   Second if the cat is rattling, I'd suspect it's not blocked, but instead falling apart inside.   The easiest "fix" until you can get a cat put back in, is to unbolt your one, bash the rest of the insides out, and then bolt it back in.   For a daily driver/street car, I am in agreeance of put a cat in the car. If it were race car I wouldn't care if it were removed.
    • No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️
    • Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney
    • I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"  
    • Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!
