Today I had noticed something resembled "animal hair" sticking out from my exhaust. I started pulling on in and it just kept coming out more and more. Must of been at least 20ft of it.

All said and done, I searched the internet and it is Muffler Insulation. This usually happens when the Muffler starts failing and traditionally on older vehicles. My truck is 2023 with 55,000kms on it.

I called the Dealer to schedule appointment for warranty work, the Service Advisor said they have never heard of this and not sure if it will be warranty. In my opinion its a faulty Muffler that is still under warranty until 60,000km

Has anyone else experienced this. Muffler 2.webpMuffler 1.webp
 

How's it sounding? If it wasn't deafening, I'd keep that crap out and have free'er flowing exhaust. 😁

Didn't know they were still using glass packs. Back in the day, we'd install brand new cherry bombs, set there and do some burnouts and get the mufflers hot and immediately take a garden hose to it and blow the glass out. 😇
 

Mine coughed up hairball too... poor little fella must feel much better now...
