Blitz all the way. I got the full stainless steel 3.5inch one. Sounds awsome. I get comments on the sound even from commodore drivers :) Has a really mean tone and shakes the top storey of my house when it goes in the garage :) On the other hand it is pretty loud. Ill let you know exactly how loud it is tomorrow :)...

jap brands are probably hype, get a batmbl 3" split dump pipe / front pipe

then get your local exhaust shop to fit and supply a hiflow 3" cat and 3" exhaust from there

much cheaper than an unfitted jap 3" cat back system

yea if you get a quality jap brand catback, you whole exhaust (turbo back) will end up costing like $1500+ but you can get turbo back for like $700 if you go the cheaper option. Ive even heard of ppl getting full exhausts for like $500 (it might have been bulshit i dunno)

After searching for a while I'm getting a Trust Power Extreme II as it's been reported to be a good flowing yet quiet exhaust. Pro Speed Racing have them for around $850 for the cat back. I originally was after a Fujitsubo but unfortunately they're out of my price range.

Yes, you can save money, but at least the off-the-sheld japanese catbacks are largely a known quantity when it comes to quality of construction, noise and (potentially) R&D. There have been a number of threads in which people have gotten a local install only to find it far too noisey or droney.

Personally i'd get a custom one.

They don't hang anywhere near as low as a mass produced Jap made one. These are made to miss everything by miles so if a flange isn't quite square it doesn't matter.

I had one done by D&T Exhausts here in Adelaide (cat and cat back) 3inch mandrel bent stainless.

When you look under the car the lowest point is the dump pipe, everything is tucked up and looks much nicer than any Jap exhausts i have seen.

Has a really nice note too

So the lowest point on your exhaust is the dump pipe off the turbo???

You've had your exhaust made and its much nicer than any Jap system?? Obviously never had your exhaust system off and had a decent look at it then...

Ask Cubes what he thinks of his stainless custom exhaust...

yes, i have only seen mine on the car, not off but from what i can see the quality is good, welds are clean, sections line up nicely.

i have a CES twin dump/front pipe which dips down slightly then back up to the cat. This is the lowest point on the system. Sorry, i didn't explain properly.

By nicer i was refering to the fit of the system with everything tucked up under the car.

I have heard plenty of people who have been dissapointed with custom systems, but i have been more than happy with the work i have had done, both on my skyline and on my old car(V8 Torana) I guess it all boils down to the guy doing the job.

i have a typical jap brand exhaust. mild steel cat back and its still in one piece, no holes, rust whatsoever. And who knows how long the previous owner and owner before that had it for. It costed me something like $400 odd when i bought it + batmbl's 2 in 1 dump/front and your easily looking at under 1k. Why go custom made for - which you have to wait, when you can just buy a 2nd hand jap one and fit it yourself.

I've never had any stainless steel components on my exhaust and personally, i believe it to be too expensive for what it is made to do - flow. On the other hand, custom made can be a hit and miss situation, like black32 said ask joel (cubes).

Race__24,

I had an exhaust done by D&T. I must admit I like the note, its not too lound and not too quiet. The exhaust is good quality APART from the dump.

Pulling the dump pipe off I was extremely dissapointed, weld splatters everywhere and they had not stretched the pipe over the flange well, this caused a V looking rise smack in front of the turbine wheel. Not good for trying to hold boost in the top end.

Mine was done some 3 years ago. I paid $1660 for a full 3" turbo back stainless exhaust.

I've got pics. Like to see them? Pics don't really do it justice but it does give you an idea of the problem.

I asked them to check it out, they said it wouldn't affect flow. cops arse. :)

Apart from the dump, I am very happy with the look, they way it has been hung and the sound.

The pics don't show the weld splatter inside the dump pipe, if you look carefully you can see a few little dots.

I've attached Pics.

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.

      Lock up the old for sale / wtb threads.

      That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.

      I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.

      If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
