The only dyno i have had done was a tuning run after the exhuast was fitted an i got 148rwkw.  Which i spose is a 10kw gain (not sure)?  But i wouldnt trust it as it wasnt a proper run.  Not much but thats everything stock so should be much bigger increase with more boost etc.

Boost comes on quicker, even when taking off quite steadily and changing gears @ around 2000rpm the bov will give a 'little' chirp, (3500 > 3800 rpm the boost is much stronger and feels punchier).  Also the induction noise is alot more noticable at lower revs.  Fuel efficency also got better by a little.  Overall i am happy with it.  except for the smell lol

Be interesting to see what it would make with K&N etc panel or pod/cai filter and 10psi.

How loud is the system? Does it drone in the cabin or pretty quiet. Does it get too loud at higher revs or still quiet enough?

its <86dba or whatever the standard is (i think mine came to 83 or 82 dba. Trevor tested it after it was installed with his sound meter and gives you a certificate to keep in the glovebox to prove its loudness. Theres no drone in cabin. Sounds quite quiet just cruising and driving normally but sounds pretty good when you get stuck into it. As i said, the induction noise is quite a noticable sucking noise which i like (as when i'm trying to save fuel i can hear the turbo sucking and change gears) (i couldn't hear this before the exhaust).

That's amusing given that Australia also has dB limits as well.  By that reasoning, all exhausts in Australia must be "restrictive" or "way too loud".  I smell a sales pitch.

To give CES their dues, they are well regarded if expensive.  

DAN00H: I was under the impression the CES dumps had a longer split than the HKS units, or is that wrong?

LW.

LW - they are the same as the HKS split dumps, no longer..... I can't understand why someone would buy the CES dumps as they are more then the HKS units. I think the most interesting are the Trust dump/ front pipe combo - they have a longer seperation (but I already have large aftermarket front pipes). I just got a set of the HKS copy split dumps for $450 + $20 postage from CRD :) included gaskets and bolts...

The only complaint you ever hear about CES is they are too expensive, never hear a complaint about quality. I got them to fit my HKS dual dragger system to the GTR as I wanted it modified to fit 2 cats. Excellent workmanship and while I was there I was checking out there HKS style dumps for the gtr. I also bawked at the price and now have a set of new HKS dumps sitting in my garage awaiting fitting. But I have to say I am disappointed with the level of workmanship on the HKS dumps. The outside looks beautiful but the inside is full of rough edges and poor finish, the CES dumps however were perfectly finished on the inside, all edges well finished for a very smooth result. You pay for what you get.......

But they do have a competetion dump and front pipe setup, I think thats what they call it, which is similar to the trust front/dump pipe setup for the gtr. The twin dump separation is much longer, and it looks very nice.

As a side note, I got a 25 awkw increase from the HKS dual dragger, it looks trick, and is noisy as hell! :wassup:

I know of a number of people who have had fitment issues with CES pipes (on GTI-Rs though).

to clear up the issue of whether their GTR pipes are anything special. they make TWO types of dumps for GTRs. One type is pretty much a copy of the HKS dumps, the other has a much longer seperation.

The reason HKS dumps are so short is because they are designed as a STOCK REPLCEMENT. so they will bolt up to your factory turbos, and your factory front pipes (or stock replacement type). again as skilled (mechanical) labour is so expensive in japan direct replacement goods are very popular. for something that only occupies the same ammount of space as the stock dumps the HKS ones are pretty good. now if you are going to change the dumps and front pipes at the same time you can do much, much more and make a nicer set of pipes like the trust ones, or the CES 'competition' ones.

personally the trust ones will be going on my car :)

If anyone finds a good -- cheap -- source for the Trust/Greddys, say so. I have been told that Advan in Silverwater is meant to be fairly good in this regard.

Edit: Don't just say Nengun/Greenline: I think we are all aware of them. Exhaust parts are big and bulky, so shipping (individual items) is expensive so local pricing is not always so bad.

LW.

we have had a CES dump pipe fitted to a R33 GTST replacing the jasma 3" that it was imported with. and the response was like night and day even with new GTRS turbo and other mods,

Had a FULL 3 1/2 inch exhaust fitted to my GTR with twin dumps, single N1 style 3 1/2 cannon mufler and hi flo cat, the engine has been fully rebuilt with new turbos fitted and i can say i wouldnt go anywhere else for a Exhaust, I believe he is the only Exhaust shop arround Brizzy with a 3"1/2 mandrell bender all others are only 3 at best,

Without the restrictor in the exhaust it is LOUD and sounds great. But for some country driving or some non headturning crusing whakck the baffle in and no droaning and VERY comfortable level.

Ive been a believer in you get what you pay for and at the quoted prices for the HKS dumps (from what ive seen) you are getting what you pay for!!!

any one go to the HOT ROD show??? would say nearly half the cars worth looking at had CES items under the hood!!!

Dont worry about DYNO gains if the system is done RIGHT you will feel the difference just by driving the car (arround town) you wont need to go straight to a dyno to find out how much "POWER" you have gained Especially with my R32 GTR you can "FEEL" the boost coming on (500-1000)rpm earlier with the new system.

Thought I'd post this list up of some quality/well-known exhaust Outlets in OZ

Sorry to dig up an old thread, has anyone had luck with dyno testing either the Trust or CES long style dumps? Trevor at CES says he has access to a stock GTR with the long style dumps that the owner has OK'd him to dyno - problem is Trevor has been pleading 'no time' for about 4 months now.

Regards

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
