Browse Caterpillar modelsGeneral guidance
In general, a muffler reduces engine exhaust noise by routing gases through internal chambers and baffles before they leave the system. Its place in the exhaust path means it is subject to heat and vibration, so condition matters when a replacement is considered.
The record lists the part as 269-6277 muffler gp with serial-range qualifiers: s/n c9e1-178 and s/n c9e179-up. Confirm the engine serial number against the recorded range before ordering, since the catalog entries are separated by that serial boundary.
