it was kinda silly..but if you pull the tube out from the firewall and then remove the sponge inside that it does make it sound really sweet when you go WOT..i dont have it anymore cause I got a JLT intake now but I actually liked the sound it made in cabin when i took that sponge out.

Wait. Am I reading this wrong, or are you implying that the sound tube can somehow break and require fixing?
I must really be taking this out of context, but it also looks like you're implying the sound tube has something to do with emissions?

TBH I enjoy the sound tube addition...I like being able to hear a little bit more engine. I even drive mine as a daily driver and the additional noise really isn't very loud unless you pull the foam inserts out. And as said you can plug it.
I don't think it was a stupid engineering choice in the least.

+1 me too, the engines not exactly QUIET, as someone else said on this thread, but the insulation on the stang is good enough that you wont hear it if there isnt a direct link for the noise to reverberate thru to you(did I phrase that right?).. I think its an awesome idea that gives you that "wow" factor when first driven lol!

Allow me to interject, if you will.
What I believe is causing OP's consternation is his erroneous belief that the tube is an unimpeded direct connection from the intake to the cabin.
This is incorrect.
There is a large diaphragm in the tube that physically seals off the sound tube from the cabin. There is no actual air going through the tube, nor is there unmetered air being sucked from the cabin into the intake.
The noises from the intake resonate the diaphragm, which then - like a drum head - carry the sounds through the rest of the tube into the cabin.
Think of it as a modified tin-can-and-a-string approach to transmitting sound.

Good I'm not the only one. When I got my car it was so freaking quiet with the A/C on low, and the windows up, radio OFF, I couldn't even tell it was on. I couldn't hear anything, that's great and all...if you drive an auto. I hadn't driven manual in 4 years, and this is bad because I drive by sound. I cant shift without looking at the RPMs if I dont know the shift points. Long story short, I slapped some Corsas and problem was fixed.
