An emission reduction device which may be removably affixed to an engine's exhaust system. The device comprises a cylindrical carcass with a beveled opening in a diagonal line in its proximal part. A bobbin is affixed in the distal portion of the carcass. A cylindrical-shaped fibrous blanket may be inserted in the carcass and the fibrous blanket may be wrapped in a wire mesh. A second fiber mesh formed into a cone may be removably inserted in the cylindrical-shaped fibrous blanket with the larger diameter of the cone positioned proximally.
