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.

    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox ! 
    • It's needed for rolling idle up, and I think it is a decider on VCT also.
    • I mean, not really. Link ECU's can absolutely still have errors from the ECU thinking it's getting a sensor it's not expecting. I would imagine the speed at the ECU level in Nistune does absolutely nothing anyway? I assume the ECU does not do any fancy TC stuff with regards to front+rear wheel speed or anything of that like anyway. Someone who uses Nistune may be more fluent in it.
