Exhaust question

[beefychicken]

Anyone have any idea.what this might be?

Story time: I noticed some threads coming out of the exhaust, started pulling, kept pulling, this is what came out. If it were the shower drain I could understand....not too sure about this.

Hoping for some advice!

Thanks in advance!

The OEM mufflers are packed with fiberglas batting. Sometimes it blows out the tailpipe. I was so curious about this that I opened one up and found it stuffed with those hairs...

There has been several posts with photos of similar issues on this forum. Most have seemed to be the 2015 - 2017 models.

Time for a new muffler maybe?

I drive mine without issues. I did not notice any sound changes within my cabin or any deviation in fuel economy. I would keep existing muffler until it has a real hole in it. You can get more stuff out. See my post

Like ftp says, keep driving and don't worry about it.

A new stainless Ford muffler's $1300. Or you can put on a Walker replacement for $100 that rots out in two years.

Figured I would jump in here. my 2018 is barfing up these fibreglass fibres now. The dealer says $787 CDN for an OEM muffler.
