2006 Gt Weird Noise

[peacebabyy]

Hey all! I have a 2006 GT that has this sound driving me nuts!!

It is coming from the inside of the car. More specifically on driver side.
I do not hear it all the time.
It seems to only be heard when I accelerate.
Its the loudest when I WOT on a dead stop or when I'm already moving.
I do not hear it on the outside.
It never use to make that sound.
The sound sounds like a suction. That's the closest sound I can think of.

The car has a few aftermarket parts.
Roush CAI http://www.americanmuscle.com/roush-cai-0509gt.html
Cervini Hood http://www.americanmuscle.com/cervinis-ramair4-hood-0509.html
Strut Brace http://www.americanmuscle.com/black-strut-brace-2005.html
Push to Start Button http://www.americanmuscle.com/sr-mustang-startbutton-0509.html

There are more, but I only posted the ones that are in the front end. I had the hood, CAI, and button for a while, never heard anything. I installed the Strut brace and after a while, I start to hear it. I have no idea what it could be. I even took of the brace and went for a drive without it, and it still makes the noise. I checked all the vacuum lines, and I do not see anything wrong. I am completely confused on what that could be. Thanks for the help!

At some point in time they started putting a induction tube from the stock air intake assembly that went through the firewall into the cabin so you could hear the induction noise the engine made. Did your car have one of these? and if so, perhaps it got moved a bit to install the brace and is picking up engine compartment noise and sending it inside the cabin.

Just a shot in the dark!

Bad strut or spring?
