The Honda 91551-ZB7-000 Muffler Stay Collar is a genuine OEM component designed for EX3300 and EX4500 generators. As a direct Honda OEM part, it is produced to the same specifications as the original component, ensuring an exact match for the hardware it replaces. Confirm your generator's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one version may be listed for these models.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this collar matches the original specification for the EX3300 and EX4500 generators it was designed for.
- Direct Replacement — replaces the original muffler stay collar with no adaptation required, restoring the muffler stay assembly to its proper configuration.
- Serial Number Verification — Honda updates parts at production serial breaks, so check your generator's serial number against the compatibility table to confirm this is the correct collar for your unit.
The muffler stay collar is a hardware component that forms part of the muffler stay assembly on EX3300 and EX4500 generators. It secures the muffler stay in position, keeping the exhaust system properly supported during operation. When this collar is worn, damaged, or missing, the muffler stay can work loose, leading to unwanted movement and vibration in the exhaust system that can accelerate wear on surrounding components.
