Here's a quick sounds clip of the exhaust, and you can somewhat hear the intake sound during the shot where I'm appoaching the video camera....

According to Carbonetic's webpage, the street verison, which is 1300kg pressure plate, flywheel/clutch combo weighs in at the same amount as stock. I have the 1600kg pressure plate, so I'm not sure if it weighs a little less. I would definitely assume it does. I couldn't find mine on the chart listed on Carbonetic's site though I know it was pretty light when I took it out of the box! Had Nissan install it when I got my engine replaced under the TSB
As far as the intake, it's a short ram design. It's the JDM Trust GReddy Intake system with the little mushroom filter that everyone is always bitxhing about. But I like it, and it'd different. Looks like this (but I have the blue filter):

As for that hallowed out sound, I would imagine it comes from the plenum and manifold. I had installed that intake before I did the whole plenum set up and the only real difference I noticed was a bit more of a growl, and I could hear that weird whistling sound which comes from the throttle body on the VQ when you put an intake on it. If any of you guys have an aftermarket intake, I'm sure you know what I'm talking about. As far as I know, everyone experiences that weird whistle. But yeah, I don't really notice much of a hallowed out sound, it's possible it could just be the video, or maybe you just hear it differently than I do.

So I conned a co-worker, I mean a friend with a 350z asked me to take a crack at his manifold. After looking at it a little longer, I think the airflow around the 2 inputs that are closest to the outside edge could be improved. So I took this one a little bit further, in this picture it's the top left and bottom right portions I'm referring to:
I followed the flow of the casting a little better:
Here's the same area originally:
This is the other one I notched out:

Thoughts? It's not installed yet, wondering if I should take the second area down a bit more.

I also shaved those down... just make sure you got the transition as smooth as possible.. you dont want to put it on and then beat yourself up weather you should have taken off that lil extra.

I did notch it in a little more, my co-worker was happy with it. Now I want to take mine off and make those little changes! He did leave me his old plenum, so I could just port that one and swap it out.
