Carbon Fiber Exhaust

RCZ

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 ) 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.
