The problems you will have is with the car being to low due to the exhaust going under the diff/drive shafts ect, the police will love to defect you for this, and also the biggest problem you will have is noise. 92 DB is the legal limit, i have a 3" exhaust right through and without the silencer i'm 102db @ 5100rpm. You should gain a fair bit of power from those mods, when doing this also get a set of pod filters or get a good pannel filter, something less restrictive. You should be able to up the boost to 1 bar and should be making around the 200awkw mark. Mine has the following done and is making a tad bit more power than that.

96gtrman i made my own 3.5' system with with twin 3' down pipes into 3.5' straight throught two the rear where at the time i could not buy the muffler(s) i wanted so as a tempary measure i cut the back off the standard unit gutted it and fitted the 3.5' into rear with the twin 2.5' standard tail pipes, the result was quiet awesome since then i have made 530rwhp with the system and i great a number of comments on the note of the gtr which is not really that loud so cruising isnt a problem/or police but it still has a nasty angry note. I used all mandal bends and also made custom 3' one piece dumps(like what tomei sell)

ps if you take your time fitting it you can have it hang at the same height as std the diff is not a problem

    • They are what I will be installing. 640s for me.
    • Hmm... From my experience you get about 0.25° camber change per mm of RUCA length change. So, to correct from -2.5 up to less than -1° (or, more than -1° if you look at the world as a mathematician does) then you'd be making 6-8mm of length change on the RUCA. From a stock length of 308mm, that's 2-2.5% difference in RUCA length. My RUCAs are currently very close to stock length - certainly only 2-3mm different from stock. I had to adjust my tension arms by 6mm to minimise the bump steer. That's 6mm out of 210, which is 2.8%. That's a 2.8% change on those, compared to a <1% change on the RUCAs. So the stock geometry already has worse bump steer than is possible - you can improve it even if you don't change the RUCA length. If you lengthen the RUCAs at all, then you will definitely be adding bump steer. Again, with my car, I recently had an unpleasant amount of bump steer, stemming from a number of things that happened one after another without me having an opportunity to correct for them. I only had to change the tension arm lengths by 1mm to minimise the resulting bump steer. (Granted, I also had to dial out a lot of extra toe-in in the rear, and excessive rear toe-in will make bump steer behaviour worse). Relatively tiny little adjustments having been made - the car is now completely different. Was horrifying how much it wanted to steer from the rear on any significant single wheel bump/dip. And it was even bad on expansion joints on long sweepers on freeway entry/exits, which are notionally hitting both rear wheels at the same time. My point is, the crappy Nissan multilink is quite sensitive to these things (unlike the very nice Toyota suspension!). And I think 99.75% of Skyline owners are blissfully ignorant of what they are driving around on. Sadly, it is a non-trivial exercise to set up to measure and correct bump steer. I am happy to show my rig, which involves nasty chunks of wood bolted to the hub, mirrors, lasers, graph paper targets and other horrors. Just in case anyone wants to see how it is done. I'll just have to set it up to take the photos.
    • What do you have in that bad boy ? Ill go with the 725cc since I'll be going with Nistune ( would definitely like more engine protection but Haltech is too far out of reach at the moment... plus, Ill probably have a pretty safe tune as its a daily, not gonna be chasing peak power 24/7 ahahah ). Are Xspurt a safe choice?  Pete's great. He didnt mention anything about traction arm length so I reckon it may be good. When I get some new wheels/tire later down the road I'll ask him about it and get his opinion on em. I heard from Gary that you've got the bilsteins too, are you running the sway bars too? and what other suspension goodies do you have installed or would recommend?
