I am a newbiew so don't flame me.. What does it do other then catch sparks? If you go with out will it shoot flames out the back? I am a trail/woods rider.. I am guessing I dont want to go with out???

 

No it will not become a flame thrower, HAHA, but it will give the possibility of very small sparks being emitted, I have ran all my quads and bikes without arrestors and I live right in the middle of a huge forest and have never had a fire.
