sparkarrestor/baffle
I took mine off along with my airbox lid and i could tell a very noticable difference. The baffle just quiets the noise coming out of the engine. The noise could cause a problem on certain trails though for passing the noise limits. The spark arrestor doesn't let sparks pass out of the muffler so it won't start a fire, most trails require spark arrestors.
