what is the difference between these three pipe sizes?

much power to gain from 3" to 4"?

sound?

steel type?

Bout an 1" to an 1" 1/2 Lol.. sorry bro

I have a 4" HKS on mine, 330rwkw no restriction should make a heap more soon to.

as a rough guide

3" ~ 300kw

3.5"~350kw

4"~400kw+

Sort of real rough guide do a search bro i think R31Nismoid has gone over it in a few threads.

Cheers,

Mitch.

Yep, that's pretty much what R31Nismoid will say.

455rwkw, 75/80mm exhaust.

It's got nothing left to give, replacement being made right now.

Sounds decent though, but that's mainly the cams

Link Doesnt work ?

Works now , sounds tough !

Be interesting to see what happens when you change it without even a retune :P

not too many too list. the car is completely standard. :thumbsup:

i dont want too many mods. in the future i might go to N1 tubos with all the supporting mods, but at the moment i just want exhaust.

Stock? And here we are thinking it's got a whole catalogue thrown at it.

Leave the stock dumps until you change turbos.

For now, get some good quality front pipes (I have hks, they're good), a high flowing cat (or none, up to you), and a kakimoto catback. It will sound SO good and be enough flow for now, or for later when you change to steel wheel turbos.

You may have people saying to get a 3.5" catback but I don't see why, when the front pipes merge to a 3" merge and your car is stock.

Steve. Did you ever get a unigroup tune before the 3 litre? we have *almost* the same setup apart from the the extra 260 cc. it would be interesting to see the results.

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?

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.

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
