2015 KTM 450 SX-F Muffler/Silencer - Screen Removal?

Recommended Posts

Any benefit realized removing the muffler/silencer screen on a 2015 450 SX-F?  On my 13 450 I removed both perforated cones and it was beneficial, as well as a major pain in the ass.  I don't want to remove it from my 15 unless there is some benefit.

 

FWIW: 1) I'm not interested in buying an aftermarket exhaust or slip on; 2) I'm not worried about starting a fire as I ride in a controlled environment and; 3) noise is not an issue as I'm on private land and not near anybody.

It's the same motor as a 14 .... so it will run better without the screen.  And, it will run even better with some mapping.
