COCACOLAD Posted December 30, 2020 Share Posted December 30, 2020 (edited) 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. Edited January 4, 2021 by COCACOLAD Link to comment Share on other sites More sharing options...
0 pmbaseball24 Posted December 31, 2020 Share Posted December 31, 2020 Can you upload some pictures of what is going on? I have never seen or heard of this. Link to comment Share on other sites More sharing options...
0 Andystoy19 Posted December 31, 2020 Share Posted December 31, 2020 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?🙂 Link to comment Share on other sites More sharing options...

0 Bad Daddy Posted January 4, 2021 Share Posted January 4, 2021 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! Link to comment Share on other sites More sharing options...

0 DTyler Posted April 15, 2021 Share Posted April 15, 2021 It is a known problem, it has happened to my Defender and there is a bulletin on it. it will be replaced under warranty. Link to comment Share on other sites More sharing options...
0 paul Posted May 18, 2021 Share Posted May 18, 2021 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 Link to comment Share on other sites More sharing options...
