Car sounds like crap after LIM Gasket install

after installing new lim gaskets my car has this loud noise coming through the throttle body, I thought it was a vacuum leak but i cant find any leaks with carb cleaner and it holds vac pressure just fine. while i was replacing the gaskets i replaced the plugs and wires aswell as made a custom intake and changed the sc coupler. Basically im looking for any ideas im lost. heres a video of what it sounds like. GTP Noise - YouTube
 


open cone lets you hear a lot more of the inside of the engine, does the noise let up after the car warms up? if so its normal.

or put your stock air box back on to make sure.
 
No... that is literally the wrong noise. Um. It kind of sounds like a bad coupler?

Or maybe your intake is vibrating in your fenderwell? It sounds like some hot and steamy metal-on-metal action. Plus a weird whining that sounds sorta like you don't have enough fluid in your power steering reservoir?
 
Its not throwing any codes btw, i just replaced the coupler and i defiantly doesnt sound like it did with the blown coupler (it sounded like rocks in the sc)
As for the intake vibrating, it made the same noise with just the stock intake tube on the tb
 


you could take the lines off the rack but that's a lot of work. I'd take as much out of the res as i could and then refill with new.
 
i noticed it had a whine when you steer and sorta does at idle but thats not the weird noise i was trying to show in the video.
 


the intake noise is what im trying to figure out, it should be louder because its a short ram intake. it sounds fine at WOT but at idle to like 3grand it sounds like a dying cat
 


if your talking about my car, it sounds the same outside.
I just cant see that as being normal, that intake noise is about 4-5 times louder than the exhaust in person. its to the point it get peoples attention in other cars.
