I installed a fast 90 this past weekend on car in sig and you can really hear the rush of air through this manifold, compared to the ls6. Has anyone else experienced this? Sounds completely different

Yes, same thing that I had happen. Lots more air noise and valvetrain noise. It is normal because the increase air volume inside the intake allows more of the "noises" to to be heard.

How loud is it? Is it annoying? Any sound clips?

Not really annoying, just different than before the install. Throatier and deeper for sure.

I've noticed a little more air noise with my FAST 90 over the LS6, but it's not bad.

Glad you posted this I'm putting one on pretty soon so now I know the noise is normal.

Yeah mine did this as well. I didnt think twice about it only because the stocker was what it replaced. I thought that it would be natural to happen due to the restrictions i was inflicting running the LS1 intake. Kinda whistles. I like it
