Heres what some of you have been waiting all your lives for... lol

It certainly is nothing impressive... I took the recording in the garage on cold startup (~1400rpms) which you will notice drop down to around 1000rpms (it will finally sit at 800rpm if I let it warm up to 145F).

I set up a pair of omnidirectional flat-response mics in stereo and samples at 48kHz for you.

Since the hood is open and the idle is high, most of what you hear is just air swooshing out of the blowoff/bypass valve.
At 26 seconds, I put my hand over the BOV. At 40 seconds I took the left mic around the back for some exhaust tone. At 49 seconds, the idle has dropped to 1000rpm and I rev it a few times. At 1:21 I turn it off and it chirps goodbye.

Unfortunately the really cool sound from these things is upon load/acceleration (also the bypass closes so that shuts up).
The mechanical noises are mostly due to the cog belt needing replaced (this one has been on for about 8 months... past the 6 month useable life expectancy) and the two cogged pullies needing aligned a little better.
Also my valvetrain is a bit clickity-clackity, ever since passing 90K miles a year ago.

For those who don't know, heres what you're listening to.

purty motor

yeah, I wish mine looked that clean, shoot I wish my car looked that clean.

Ok, now put some mics under the hood and take it for some WOT runs. Then we'll giggle and pee ourselves.

I never understood how people's cars stay that clean. Mine looks like crap and half the junk that is on it won't come off.

I don't know how mine stays clean, but it does. I'd tell you if I knew how it does it. I just do a quick wipe down on the underneath of the hood after wash and quick wipe where I see just sand/dirt particles. But that is about it.

Nice, but did I hear a exhaust clip in there as well, it sound like it.

nice

Very nice!!

Also, very clean under the hood there!
