It's not a question of performance.

Same shit.

You NEED a flex pipe to absorb movements in and around the exhaust system.

This eat's up stress that would otherwise be put on exhaust manifolds, exhaust mountings and so on.

id go with the cheaper one with the flex joint aswell.

and with all cheapy stuff the jigs they use are often not rite. so with the flex you have that extra margin for error. just make sure you have the g box exhaust hanger fitted..

Indeed it could pose a problem.

Get things hot enough, they can warp and so on with too much weight.

Could warp flanges and so on. Extra stress on manifold bolts and the like.

I've seen a turbine housing actually twisted due to similar issues with heat/weight (was circuit, 400rwkw+ setup though)

It does happen, my Exhaust hsg warped and I had to replace the hsg

Does any one want to group buy in it??? Ill also purchase one and gaskets to suit if any ones keen, Im going to replace my stock Nissan exhaust and Add a 3inch kakimoto racing pipe behide This GKTECH RB25DET Front/Dump pipe http://www.gktech.com.au/front.asp?pid=11&...uctID=R323-FRDU

^^ about that. i have no gbox to exhaust support on my system. its a stainless turbo back with no flex pipe.

can it be a problem?

i would have one put on there, my dad's snapped off from the back of the turbo!

Lol, saw them on ebay and decided on buying 2 for the RB26dett

also found cheap same-priced 3" turbo dump pipes, so paid for 2 of those as well.

Will merge the 2 gktech's into 1 3" outlet, inlieu of cat-converter pipe, to mate up to the 5zigen cat-back I have

:)

yeh - whys that - wont they work (ie bolt on) ?

I thought they did. . .

or are you saying they are crud.

to be used only a few times per yr on a R32 track-sedan

the rb26 engine will be rebuilt in a couple of years time after some Mallala sessions, and go into my Stagea

Ive bought a GKtech front split pipe and put my exhaust on overall it feels like i cant get my auto to tramp it as much down low it could be because im not catching the revs properly with my right foot. But about 3 grand till red line i do notice a fair bit more pull (Note i'm running a stock rb25 turbo) Just a lame arse question what size are these baby snails are the a T2 or T25 size or something all i know is there bloody small compared to my T04e i have in the cupboard. Im not game enough to put on my Ebay t04e snail on my car lol

    • Just had this happen to me too.  R32 GTR.   Also broke "just before going out onto the track" - someone up there is looking out for us... Very scary since I was about to do a narrow street course with zero run-off and curbs everywhere. Many people on here upgrading to billet uprights and R35 bearings?   Or buying new OEM knuckles?  I am not keen to replace with another s/h 30 year old fatigued part.
    • Top off with distilled water and see what happens. If you keep losing coolant then you know to start looking.
    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
