I currently have an aftermarket dump pipe and 3" Catback exhaust looking at gettin the front pipe to make my exhaust 3" Turbo back what is the best choice out of the 2 examlpes i have given?

[allthewaytotheskyline]

go the gktech as they are identical design in both but you have the extra movement (with the flex) which is better then not having.

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..

^^ 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?

[R31Nismoid]

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

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

http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...e=STRK:MEWNX:IT

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

http://cgi.ebay.com.au/ws/eBayISAPI.dll?Vi...em=350324770735

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

[rb30dett]

Tangles: Did you buy the dumps for use on an rb26?? I hope not......

[Tangles]

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

[rb30dett]

Pretty sure they are different like the housing bolt pattern is upside down. Some of the old HKS turbos use the silva housing pattern etc.

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
