When I got everything done and cranked the car everything ran fine no leaks, etc but when you cut the car off, I hear this "click" or "thump" it sounds hollow almost.

Anyone have a idea or can I post a video here?

VIDEO ADDED....

I know I read somewhere in this forum that a guy had this same issue, or a couple guys. I personally haven't had this issue with mine.

The noise is coming out of the cai filter.

I've checked all the vacuum lines they're all routed correctly according to the pics I've seen.

That's not the same issue I have.

Listen to my video I posted the link to above. It happens right after you cut the engine off. The sound comes from the filter but may be coming from the throttle body itself? IDK

Thanks for looking though.

Sounds like air being forced past the TB. I have the stock mani and TB with a steeda cai, if I listen closely, I can hear my TB open and close. I never knew why. I guess there's residual pressure in the intake

It's a diverter valve .the nipple on the front of the manifold is a vacuum chamber . When you (key off) the vacuum of the engine stops and releases the check valve . With the stock intake there are two check valves in the same line . With the gt350 , one is removed .
