I removed mine and now I have a high pitched whine.

You should get no whine if you plugged it and the firewall properly and removed all parts. I am planning on machining a thick piece of plexyglass to a diameter matching that of sound tube where it enters the intake tube once I get the 2011. Clamp it in similar to how the sound tube is clamped. Have used this technique many times to delete resonant chambers on intake systems. What I do wish is that CAI manufacturers would make a clean tube option with no provisions for the engine compartment snake ! You don't need the stinkin thing with louder muffs and CAI.

That was the stupidest thing that for did starting in 2010. I took mine off the firewall and plugged the firewall. I wish that these aftermarket companys would also offer one that did not have the provision cause it would look alot cleaner, the only company I know of offering one without it is the JLT cai system.

IMO the sound tube is worthless.

What is the purpose of this tube? Does it pull intake air from the cabin? Why?

+1, thats always a good replacement.

Good question. I think it's just a novelty? Not sure. I like the sound myself.

so you can hear the engine noise louder.
if you want louder, just do exhaust.
i would want my Mustang to BE fast, not just SOUND fast.

i like the noise to be silent inside the cabin and noisy from the outside.

Worthless and a total eye sore to look at under the hood. If I was to buy a new GT I would open the hood and rip it off right in front of the deal and hand it to him before I even drove it off the lot.
