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?
