Filter Replaceable Full Exhaust System is attached but indeed there is a gap between Filter and Exhaust, so it seems to be possible to replace it and indeed this Wrench could also be fitted. But Ratchet does not turn .... No matter how I can not enter Ratchet 5 more after it. I turned it with my own tool which we made suddenly. This product itself is not bad, but the compatibility was bad. Those who have narrow Filter circumstances should better consider other types such as Band expression.
