CES Racing full exhaust claims?

[zymotic]

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 - 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...

[jlnewton]

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:

[Abo Bob]

It's the GTST and GTT ones where the split is much longer. I think it's worthwhile for these cars.

[DAN00H]

JL - sounds like the twin system was a good choice I still think for the money I'm happy with the HKS ctyle ones I got from CRD. I can easily clean up the insides with a die grinder. Saved a few hundred $$$, better in my pocket.

jlnewton: I seem to remember some mentions of the CES units cracking. This was quite awhile ago though. (Just to be clear, I have no personal knowledge of this).

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

[lwells]

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.

Hmm - that doesn't sound good....

[Beer Baron]

Lucien, i think the trust ones can be had for a pretty good price from autobarn of all places!

for me I will buy them in japan and carry them home seriously.

[doubled]

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.

All I've ever wanted to know is if the long style dumps are worth the extra cost over the short style. Corky Bell's book suggests wastegate pipes about 400mm length, even the CES ones are shorter than that.

[Scooby]

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.
