Sound Tube Delete parts list
Yes I do and its not good for air to get in after it because you will run very lean. To answer your question it senses O2 or the amount of air flowing through the intake at that point, any air getting in down from that point is not metered and will result in a lean mixture. Taking the baffle out results in an open tube and pulls air from the passenger compartment. It is the same as a leaking manifold gasket.

Oh, and yes, it will make the car run crappy and most likely cause a check engine light too ... for LEAN condition

And if your engine is sucking crap in though that tube then you need to clean your car...
It's actually freaky when you remove the sound tube, when you realize just how much fake noise it added to the cabin. I always was of the opinion that my car was actually kinda loud. Not hardly at all. Especially at idle. With the windows closed and the top up, even with the radio at a low murmur I can't even hear the cars idle.
All I said was sensor, Texas thought O2 sensor. I am totally amazed that you can't understand that, oh well. If you don't pull everything out, leave the diaphragm and maybe some of the sound deadening you would be OK. Last comment, its not crap but the unmetered air that is the problem but you won't understand that either. I'm out of this one.

To the op. You wont/cant run lean by pulling the filter/baffle out of the sound tube.
Me personaly, i would delete the tube all together. As it is ugly and the 5.0 engine bay looks alot better without it.
To those who want to experiment with the sound tube, do not put it back together without the diaphragm. Play around with the baffles all you want and leave that part in, you shouldn't have any problems. I do have a 5.0 2013 Mustang with sound delete.
The only harm to be done is any debri from the cabin. No chance of lean condition
Also. Thought you already posted your last post

Or is this a "p.s." post?

Grabbed the parts to do this last night, not sure who did the measuring saying the outer diameter of intake side hole was 1.5 inches, but you may want to relearn measuring. I grabbed a 1.5 inch cap and a 1.25 inch cap and both were too big. I ended up cutting the piece of rubber off the intake side and using it as a spacer/gasket, which ended up working really well.
