2008 Discovery 40X, looking for a new muffler

The muffler on my discovery is pretty rusty, where do you search for replacement? Thank you in advance.

Freightliner chassis w/ 350 Cummins ?

  • Since it's on a Freightliner chassis, the easiest thing to do is to call Freightliner with the VIN # in hand - they will want the last six digits.

    If it doesn't have a hole in it, I wouldn't worry about it. My 2005 Excursion muffler is doing fine. If you put a new one on, it will probably look the same in two years from the exhaust heat.

  • Try most any good muffler and exhaust shop. If they don't have it in stock, usually they can get it quickly. I needed an exhaust pipe, my local shop cut it off, bent a new one and had it back on and ready to go in just a few hours. And with a new stainless tip on it! Local shop with a truck bay.
  • It’s Cummins, not Cummings.
    Muffler or exhaust tip?
    I bought my exhaust tip from Fleetwood.
