This is the muffler and heat guard / shrouds from my 3011 Honda mower I parted out due to a bad transmission.
You get all pictured, including:
MUFFLER 18310-763-B03 ($234 new)
PROTECTOR ASSY., HEAT (UPPER) 18305-763-A03 ($80 new)
PROTECTOR, MUFFLER 18321-763-A00 ($63 new)
PROTECTOR, HEAT (LOWER) 18344-763-B01 ($63 new)
Everything works, but you will need a new gasket, which is part number:
5 GASKET, EX. PIPE 18333-ZE3-800 18333-ZK6-Y00
(they run about $5 new).
The muffler is solid. No rust out. Minor surface rust on these parts as expected but overall excellent condition.
