Description
Overview:
This Non Genuine exhaust muffler replaces OEM 89966 on Briggs & Stratton small engines, including 2HP and 3HP series. Built with a robust steel body and a durable black finish, it is designed to withstand high temperatures and everyday use. The unit screws directly into the cylinder head using a standard 1/2 in BSP thread (approx. 12.7 mm nominal size; typical thread outside diameter approx. 20.96 mm), making fitting straightforward. A 14.5 mm bore supports smooth gas flow while helping to reduce engine noise and harshness. Suitable for compact equipment powered by horizontal or vertical shaft B&S engines, it provides a practical, reliable replacement when the original muffler has rusted, blown, or become excessively loud.
Key Features:
- Non Genuine replacement for Briggs & Stratton OEM 89966
- Strong steel construction with a protective black finish for longevity
- 1/2 in BSP screw-in connection (approx. 12.7 mm nominal; ~20.96 mm OD) for a familiar fit on many B&S heads
- 14.5 mm bore balances flow and noise reduction for stable running
- Helps cut exhaust noise for quieter operation on site or at home
- Quick, tool-light installation for routine maintenance and fast turnaround
- Compact canister form to clear shrouds and engine covers on small machinery
- Suitable for regular service conditions in gardens, workshops, and light construction environments
Typical Applications:
