Mustang GT - anyone put on a quieter exhaust?

I have an Ecoboost now. I added an MBRP Street cat-back exhaust a month ago because the stock exhaust sounded like a Honda 50cc motorbike. The MBRP is terrific in sound and increased MPG. Nice purr now with a rumble when wanted.


I am thinking of getting a GT next purchase, but I do not want something that is LOUD. I've read several places where drivers were not happy with the stock GT sound. Has anyone added an exhaust to quiet the exhaust a bit? I want the power of a V8 next time, but I do not want to sound like a teenager; I'm 73 years old guys. <g>
I know there is the "active valve exhaust" option, which my GT will have for sure. I figure that will allow me to quiet the exhaust enough I'll not be "self-conscious".


Thoughts?

At 73; don't you want the exhaust to be a bit louder, so you can hear that glorious V8? I know at 59, I do! :-)

half joking about the above . . . . I think you should test drive a GT before you worry about it too much, I think most of the people who were not happy with the stock exhaust wanted it louder . . . the active exhaust with "quiet" mode would probably do the trick.

What you remove is the sound tube that looks like this:

The removal kit supplies you with a rubber plug for the fire wall and a rubber cap and hose clamp for the air intake. This will quiet the noise inside the cabin.

On my 2018 GT, after I got tired of hearing the piped in noise, I just removed the tube from the intake tube, put a Quarter on the end of the nipple, wrapped some electrical tape around it to hold it into place, and then re-installed the tube. The tube is still there, but the piped in noise is gone. However, I think the OP is concerned about the actual exhaust noise at the end of the pipe.

Interesting. I never heard of such a kit, thanks for passing that along to me. However, I'd want the outside sound tempered down a little also, not just inside the cabin.

Anyone know if the GT's "active valve exhaust" affects the sound that is "piped" into the cabin?


I did not know the Mustang GT even did that. I read somewhere the EcoBoost did that, but I thought that was somehow electronically produced? Seems like a weird thing for Ford to do, but then cars have gotten away from the basics many, many years ago! Both for the good and the not so good. I remember well the nice sounds the V8s made in the 1960s; pleasant rumbles, the engines sounded so powerful. Now of course we know they were not all the powerful compared to today's engines, but they sure sounded sweet to a "kid's ears". I was in my early 20s in the mid 1960s; not exactly a kid. <g>

I don't think so -- as far as I know, there are no moving parts in the "sound tube."

The sound tube was added in 2010, when Ford increased the cabin sound insulation . . . I guess they thought we still wanted to hear the intake and other "noise" coming from under the hood.

Personally, I kinda like it . . . I miss the moan of an open 4-barrel carb and the sound tube makes up for a little bit of that . . . but I have never tried removing it so don't actually know if I'd like it better with or without; and there is probably a big difference between 2010 and 2018.

you're welcome,

My new 2020 GT/PP has the active exhaust system which give you 4 options. It has a quiet mode which makes the car sound like a sewing machine - horrible option.

Well yeah, but what about the other (3?) options?

The Normal Mode makes me smile, the Sport Mode gives me a bigger grin and the Track Mode makes me laugh out loud.
