Well, I was messing around under the hood and "unplugged" the sound induction tube on my 2010 GT. I was reading that the tube is plugged with insulation so I wanted to see if I could remove it. The insulation plug is just inside the tube at the firewall. I simply pulled the tube out of the firewall and removed a 1 1/2 plug of foam insulation. Also, there is a small caplike plug on the inside of the car just behind the clutch pedal that needs to be removed. It looks like a small white/gray flat cap. It simply pulls out. The car sounds much louder now and the cabin growl is significantly more pronounced. Nice free sound enhancing mod!

during normal driving, it doesn't really sound any different. The increased "growl" is only noticeable at higher rpm's under throttle.

Did you like the way it sounded? I think it sounds pretty cool and I'm going to leave it that way, at least for now. I want to drive it for a few days to see what my overall impression of it is.

The sound induction tube is specific to 2010-2011 model Mustang GTs. Ford engineers found that the overal tone of the 2010 Mustang GT was too "quiet". The induction tube is a plastic tube that is connected from the intake ducting to the firewall/cabin of the car. It transfers sound from the engine to the cabin compartment to help increase the perceived engine sound in the cabin. It is simply a hollow plastic ducting type tube. There are no sensors in the tube. It simply functions as a sound resonator. It comes plugged from the factory with a foam stopper. What I described above was the removal of this foam plug to make the ambient sound in the cabin a little bit louder. This sound induction tube was not present on earlier Mustangs.
