Carbon Fiber Exhaust
 

since I mentioned this on another thread, i guess i should make a separate one and not hijack the other thread...lol

this exhaust system is currently available on the G37, hence it has the same engine...so maybe Fast Intentions will make one for the Z.

here is a video clip


Edit: HTML is off, how can anyone experience the joy of an exhaust clip???? :confused:

and some pics

so, ponder on this while I try and find some dyno sheets...lol...and don't forget to give me some rep points... :tup:

Follow these simple steps

or just post link of the video and i'll embed for you.

BTW, exhaust looks nice!:tup:

^^ there, i did....yay!!!

LOVE that sound.

Reminds me of my carbon ti. I really dont like the way they did these though....dont like the design at all.

Sounds prettty grood!

why so, explain pls

Sure,

First of all, the idea of having carbon wrapped anything is pointless. Carbon should be used to reduce weight, not to make things look pretty. Nothing wrong with it looking pretty in the process of shedding weight. Those are just carbon sleeves around a metal canister.

Secondly, it is great that its a true dual, but the lengths are unequal, which could be a good thing or a bad thing.

I dont like the way the resonators dont seem to flow with the rest of the exhaust, they are just welded on there. Looks like they dont fit together. Also, 4.5" tip with 2" or 2.5" piping the rest of the way, why not just make it as free flowing as possible and make it all 3 or 4". The tips look like they just bought them at autozone.

It just doesnt look smooth to me, looks hacked together from different components and I'm sure they charge a good chunk of change for that. Truth is I could go to my local muffler shop and have them build me the same thing. Then I can make it heavier and more expensive by adding carbon sleeves.

the shop said it is not Carbon sleeves, the canister is really made from CF.

it is full of bends at the muffler section but the rest is pretty straight forward

here is a pic of the CF exhaust

and here is a pic of the stainless canisters

Ask them what the weight difference of the two is. Also whats the weight difference versus stock.

^^ okay, i'll ask them

From here the build quality looks pretty good. How do the carbon canisters seal on the ends? It seems there's very few screws, and they are radial screw holes, which usually doesn't provide for a good seal (certainly never did on my motorcycle exhausts, which were FMF and such, not el cheapo stuff).

1) The mufflers are full CF

2) The resonators don't stand out that much in person. It's just the angle along with the camera flash that makes them so obvious.

3) Why would anyone do 3" exhaust piping on a naturally aspirated car? And 4" piping? ...not even high powered turbo cars have the need for that.

4) The exhaust looks anything but cheap. The whole design just looks very classy, which was one of the reasons why it was such a big hit on the G35 community.

You really need to see/hear the exhaust in person. That doesn't mean everyone will like the design, but its just a quality exhaust. (The welds are also superb).

Agreed, there must be something we are missing. Those little screws would not be able to hold it together and keep it from leaking. Hmm

Carbon just isnt good for exhaust components either...

Full CF? OK, how are they held together? IE, how is the CF bonded to the metal?

So what are the weight savings?

Actually, 3" is quite common in the FI world and so is 3.5". Usually you dont want to go too big on FI cars or you will suffer from lack of backpressure. The point is that I don't like the stop-go airflow walls that there seem to be.

Notice here the tapered ends of the mufflers vs. the flat ends of the one from fast intentions.

Do you have one? Sounds like it hehe. Classy is subjective in the G35 World, no offense meant, I wasn't implying anything. How much is this exhaust anyway?

I will see the exhaust in person I'm sure. When that happens I'll be able to really tell you my final verdict.

Also, hopefully I can get a hold of one for testing purposes.

Welds do look good.


Also, where are you getting your information?

Not sure. You would have to ask Tony @ Fast Intentions. This is what he stated from his own words at MyG37.com:

The Carbon Fiber is not an overlay. It is the actual case to the muffler. It is for aesthetics and weight savings...
He stated around ~25 lbs over stock.

I know. But that wasn't what you were referring to and what I was replying to. 3" is fine for turbo's cars. But not for naturally aspirated vehicles. And 4"? I haven't even heard of forced induction vehicles using that sort of piping for the VQ.

Yep. I have the older version (stainless steel, oval mufflers). I got a hell of a deal for it (almost free :eek:) from a friend.
I've been around the G boards (G35driver, moderator) and Myg37.com (though im not that active there) for a while. I always do alot of research into a product before I pull the gun. And the Fast Intentions exhaust was just top notch in comparison to other exhausts out there. Ofcourse, the subjective areas of the exhaust will always vary from person to person.

I also have their resonated test pipes, which are also great quality pieces. The resonators are excellent and the welding is just very professional.

You can look into the Fast Intentions exhaust at Fastintentions.com or, for more information at the G37 boards (Fast Intentions cat back Fall/Holiday sale (All Cat backs, prices slashed)!!! - MyG37)

it's around 1400.00 USD for a cat-back CF exhaust system






many ppl decided to buy a cat-back system from Magnaflow b/c ppl were getting them at less then 500 shipped.....which seems like a good deal !

For a simple catback? I mean I know its dual and all, but 1400 is a little steep for something of that quality. I'd pay $1400 for an ericsson or an amuse titanium catback.

$500 sounds a tad low for a dual catback. I think the sweetspot should be around 6-800 for a really nice catback.

some ppl got 500 for a catback b/c we found a loop hole on the site....lol

reg price was a bit more...lol...then they found out and raised the price...hahaha




1400 is a bit much for an exhaust...i agree

Nice, but with the stock rear bumper, you can't even see the CF. If I was more interested in look, I'd rather have titanium, not to mention for weight savings and sound.

I have this exhaust for my G37S and it is kick a$$. The CF is not a sleave. Tony at fastintentions is a great guy call him up he will answer all your questions. Having a slight ses light issue with the HFC some get it some don't and then the non-foulers work on some and some don't but I know he is working on a fix 100% and I know it is going to work but I cannot tell anymore as he asked me not to. He will be making this for the Z soon.

so, he is making one then??

I need to talk to him but last time on the phone he said he would be.

^^ someone clearly did not read my email then

hows that?:confused:

^^ someone that you talked to

oh ok well I have not talk to him in a while so maybe things have changed.

^^ ask him to read my email...lol

hey i see my car.. lol keep a look out for this system guys... ;]

^^^ which was the whole point of making this thread

Wow,

You must not know anything about my company nor our exhaust systems. First of all, what resonators are you referring to? The resonated X Pipe in the center?

2) Our exhaust system is 2.5" all the way through. Those tips are 4.5" on the outside however they have a 2.5" core. This exhaust system has been finely tuned for the 350/G35/G37 and I can guarantee you when it is released for the 370Z you will want one!!!:driving:

If you don't like the Carbon Fiber, that is why we have the round stainless steel version.

To put the issue to bed, the Carbon Fiber is not an overlay, it is the actual case to the muffler. The muffler weighs just over 1 pound and IMHO it blows Titanium away. The exhaust DOESNOT leak out of the end caps. The design is perfected and these mufflers are on hundreds of different vehicles.

The tips are anything but Autozone. You shouldn't be so quick to criticize especially without seeing the products in person. We use only the best quality products for all of our components. We have done so for over 9 years.

To sit hear and say that a true dual mandrel bent stainless steel exhaust (Carbon Fiber) system should be around $800.00 is a pipe dream! You must have no idea as to what goes in to the build process or the time. Compared to the other high end exhaust systems, $1,429.00 is very reasonably priced.

Look, I have no intentions of coming here and making enemies, my goal is to build all of you a superior exhaust product. Just don't be so quick to judge us or our products when you know nothing about them or us and especially with the reputation that I have worked so hard to build on the previous cars.

If you have any questions please feel free to contact me...

Very nicely said tony.. Once the exhaust is complete and on my car.. people will be drooling ;) this set up is truly the real deal guys.. i have seen/heard about 10 different set ups for the G37 and this one honestly takes them all. EVEN HKS.

^^ I take credit for starting the hype of this exhaust to the 370z ppl

i take credit for it being made... ;)
