Removed the sound tube. I find it to be a much more pleasant sound without it.
I’m considering removing it, why do you say it sounds better? Did you use a block off?

I wasn’t sure what to expect from the sound change. In fact, I was having trouble convincing myself I could even tell it was there to begin with. I didn’t remove it for the sound, but for the looks in the engine bay, but also really curious what the sound change would be. I have a non active factory exhaust with a steeda h pipe, so a little louder than normal. That being said, the difference is that it’s less noisy. Normally there’s some kind of audible distraction from up front. Couldn’t really put my finger on it though. With the windows up now, all you hear is the exhaust note, not anything from up front. I actually would be interested to hear what the sound tube sounds like if it could be recorded by itself, but probably not possible. I bet it sounds like ass.

I did use a firewall plug- and this is going to sound hackish- I cut the pipe about 1 inch from the firewall end after I took it out and used a heat gun to melt the plastic pipe closed. Went over the pinched end with a plastic welder to seal it shut, then put it back in the firewall. I thought I had the proper sized plug but was mistaken, so improvised. It’s temporary till I get the right size in a day or so. A rubber cap and a hose clamp goes on the intake pipe.

But what will you do if you want to put the sound tube back??? Lmao

When I removed it all I noticed was a bit less drone from my exhaust at the time.

Interesting… might be worth trying and see what it’s like..

Gotta do what you gotta do to make stuff work in a pinch.

Hey Mike,
Where does this elusive sound tube poke into the cabin? Is it up under the steering column?
Wouldn't it be easier to leave in place and plug from the cabin side?
Any pics? Thanks,
Bob

Not me, but my (UK) neighbour :like:

He's just sent me this of him living it up in Fort Myers :

I get on with Jerry really well and he loves my Mustang - which is fortunate as he's my closest neighbour and the only one likely to moan about the exhaust ... lol

I'm not sure how his rental is kitted out, but I've just text him how to find sport mode and instructed him to let it eat :cwl:

WD :like:

@Willistylz I got my hood on Tuesday and was able to install it without any issues. I know its Shadow Black and thats a easy color to match up with but the color looks great. I am not sure I love it like I thought I would, but maybe it will grow on me. I also added my new shift knob from Twisted Shifterz which is pretty nice.

From what I understand, it is behind the accelerator pedal assembly, so that has to be removed to plug it from the inside. Some people have done that. But in terms of leaving it installed, I was mostly removing it for appearance reasons and to simplify the engine bay. There are no fewer than 6 locations on the sound tube where a grommet or hose clamp is used and each is a potential vacuum leak down the road. Also, it sort of obstructs access to some things on the driver side. I didn’t take any pics, but there are plenty on here of people doing the same thing. I don’t have my car with me today or I would get some. I will attach a pic of what I removed as it is still sitting on my toolbox here at work.
