Muffler Warning and CEL?

[M1ryguy]

go get the reflash , use the mbrp can , it's an exhaust sensor issue no big deal , also if you shut the sled off when you throw the code and restart you'll be fine , mine seemed to only throw the muffler code when bringing the sled up to operating temperature , the mbrp cans are the worst for throwing the code but like I said go get your reflash and you'll be good to go

Had same issue with npp can on a 14 xm. Pull out probe, clean it up. Re-install with thread sealant and zero issues. Believe it was from first start-up since the engine was fogged last spring.

My '14 did the same thing all last year with the MBRP trail can. Got the dealer to flash the update this fall and no exhaust codes now.

Took my sled to Martin yesterday, got the reflash. Running the MBRP with no issues, thanks everyone!
