2021 Defender max XMR bulging muffler.

Has anyone experienced their muffler bulging? from the rear it looks like the muffler was creased. When you inspect it you can clearly see it has almost doubled in size.

Can you upload some pictures of what is going on? I have never seen or heard of this.

I need a picture of the muffler, even if the exhaust was partially or completely plugged the amount of pressure required to expand a muffler would kill the engine before the pressure could be produced.

Is the engine running okey?

I uploaded pictures. the crease was created by the expansion.

I have been running mine at 75% throttle-100% with tracks on and fully expected something like this to happen, but it hasn’t. 
I am pretty sure they’ll warranty it for you!

Looks like it’s sort of a common problem?

It is a known problem, it has happened to my Defender and there is a bulletin on it. it will be replaced under warranty.

from what i understand it is a factory recall on the mufflers. the catalytic converter is also in the muffler and welded incorrectly. mine did the same and was just replaced under warranty. only a defender issue. hope this helps
