Hi all, hopefully someone can shed some light, I fired up my 2016 Commander DPS and went for a short spin around the block the other night, then when I got back the muffler was red hot.. I was driving with the grey key, but it seemed excessively slow and sluggish.. any clues would be appreciated..

Pull the spark arrester out and clean it . It’s behind the turn out on the driver side.

And being it’s a 16 your cat maybe plugged up. So could be time for a new muffler .

So you pulled the spark arrester out or you just ran water through it?
No Ace, couldnt get the down pipe off because the nuts that must be tacked on the inside snapped off, so the hex screws just spin..turning into a disaster, now I'll have to cut it off and tack weld it back after checking the spark arrester..

They have thread setter nuts crimped in the muffler . They are bad about rusting to the bolts . They can be replaced . I used stainless bolts and had no more rust issues .

Was also wondering if you particular model has the cat at the inbound side of the muffler and was that an issue or not.. what year is you Commander, do they all have a cat in them?
