Engine Compatibility

The MUF0626 is intended for select:

• Briggs & Stratton Intek V-Twin engines
• Briggs & Stratton Professional Series V-Twin engines
• Vertical-shaft configurations
• 18–30 HP applications
• 40xxxx model-series engines

Important: Vanguard Compatibility

This muffler is not listed for Vanguard Series engines. The current sales listing specifically states that MUF0626 will not fit Vanguard models.

Because exhaust configurations can vary within the same engine family, always verify the complete engine model, type, and code numbers before ordering.

Filter-Side Exhaust Configuration

The MUF0626 is a right-hand/filter-side muffler configuration. When installed on the intended vertical V-Twin engine, the exhaust outlet is positioned toward the oil-filter side of the engine and remains above the engine mounting plane.

This orientation is important because similar Briggs & Stratton engines may use mufflers with different outlet positions or mounting arrangements.
