FMF PowerCore 4 Silencer for 2019-2022 KTM GasGas Husqvarna 250 4-stroke models — see below for fitment list.
Also fits 2019-2022 KTM 350SX-F and 450SX-F models (and GasGas + Husqvarna equivalents). I’ve personally run these on 2022 KTM 350SX-F and 450SX-F models so I know this to be true.
I’ve verified with FMF that this silencer/muffler is ~ 40mm shorter than the OEM muffler on the 350s and 450s, but is the same as the FMF 4.1 RCT top-of-the-line muffler for all of the 250-350-450 models.

Also includes spark arrestor insert for those who need to ride on forest trails where a arrestor is required.
The P/N is 79105979002.
