PCT No. PCT/US80/00440 Sec. 371 Date Apr. 17, 1980 Sec. 102(e) Date Apr. 17, 1980 PCT Filed Apr. 17, 1980.A stack (14) is attached to extend upwardly from a hood (12) in surrounding relation about a muffler (18). A sleeve structure (28) surrounds and holds the muffler (18). One or more tabs (30, 32, 34) extend generally outwardly from the sleeve structure (28) towards the stack (14). One or more corresponding brackets (36, 38, 40) extend generally inwardly from the stack (14) towards the sleeve structure (28) and generally adjacent and parallel to the tabs (30, 32, 34). The tabs (30, 32, 34) and brackets (36, 38, 40) are removably secured together. The muffler (18) is relatively quickly attachable within the stack (14). The stack (14) serves to direct noise upwardly and to keep people from touching the relatively hot muffler (18).
