FMF 4.1 slip on
Great sound if you want to feel the piston in your chest. This slip on is on my boys bike and now I really do enjoy riding next to him so feel the thunder even though I am on a 2 stroke. The installation is simple and quick for a KTM 250 SXF, there is a little more wiggle as the FMF uses only one of the factory mounts at the rear of the silencer. Maybe this will save on damage if the boy decides to ride on the side of the bike!
