arrestor goes at the end; fuel can ignite within the exhaust at just about any point, cling to loose carbon and be expelled out the tail as a nice little brush fire starter. when you do a fast lift from full throttle, it's going to dump fuel into the exhaust. it's not so much something lit and hot traveling the length of the system, larger particles throughout can ignite after getting wet with fuel. the screen impacts and or breaks them up enough to put the fire out so to speak. ever turn a muffler into a can grenade? ))) it'll wake up a few blocks. )))
