Im sure it will be safe and reliable. Like a previous post said the hum will be louder, i agree. But overall I would say it'll be worth it once they get done testing it. Z1 cant afford a product to fail on them and get a bad rep for their parts with recalls.

Total guess on install. Id say 1.5 hours at $75, 112.50. Z1 told me the bolts holding it to the rear end side are difficult to tend with...

I currently don't hear any hum when driving at a low or high speed, why would they be a hum from this mod ? 370Z and GT-R Exhibit this component, is their any hum......I'm curious to know why would they be increase in the noise level.

kind of the same concept as a lightweight flywheel, they mainly just sell you a flywheel without a dampener. I "hear" those who change the flywheel notice a little more vibration and hear a little more noise.

I guess I didn't make myself clear enough
The next off topic post (ex: exhaust velocity) will get you a nice time off the forums!

Already posted in the carbon fiber driveshaft thread but...Just installed mine.
Quality:
Great, VERY light over stock. I was pretty amazed. I'm very happy with it.
Installation:
Simply pull your exhaust off, unscrew 4 bolts, swap out the stock unit with the new one, and bolt back in. It takes longer to get the exhaust off. I was in and out in less than 45 mins.
Performance:
The car definitely pulls harder and probably "gained"(i.e. got back) a couple of felt horsepower. Nothing crazy but you will notice a difference. I'm all about light weight components as our car is heavy already. For the price, its worth it to me.
Noise:
As far as noise, I noticed it is every so slightly louder(hum) at low speeds and deceleration. I mean barely. Keep in mind I have had my shifter rubber/noise dampening out of my car because I just installed a short shifter and was waiting for some carbon fiber products from tony at CF elements. As such, I did not have any noise dampening between me and the driveshaft/road, only the rubber piece not screwed down. At high speeds, nothing is noticeable and I'm sure you will not hear the difference at all with your shifter area fully assembled. I have also recently had a noisy exhaust problem and can't hear anything over that. Im switching back to the stock manifold and cats so it will be better.
Vibration:
I have not felt any vibrations at any speeds whatsoever. I have not gone over 85 yet though, I'm a little cautious on highways now cops have been out in force around me!

cf is better than aluminum idk why he said that, hence why they put it on the 370z hence why the gtr has it. i have priced 2 places that custom make carbon fiber and they are around 900. the difference between them wouldnt be worth the money unless you like to be a one upper lol
is Z1 coming out with their own CF driveshaft?
