Westwood Mufflers & Exhausts
Westwood mufflers and exhausts reduce engine noise whilst directing hot gases safely away from operators and equipment. Our muffler inventory includes Westwood mower mufflers, engine exhausts, replacement mufflers, and complete exhaust assemblies for walk-behind and zero-turn models. Westwood Spares stocks Westwood muffler assemblies in stock with proper spark arrestor screens and heat shields for residential and commercial equipment, providing worldwide shipping on all exhaust orders. These essential engine exhaust components feature steel construction with internal baffles that attenuate sound levels meeting noise regulations, whilst spark arrestor screens prevent ember discharge reducing fire risks throughout extended mowing operations in dry conditions.

Frequently Asked Questions
What causes Westwood mufflers to fail?
Muffler failures result from rust perforation from condensation and chemical exhaust exposure, impact damage from debris strikes, cracked welds from thermal cycling and vibration, or carbon buildup restricting flow causing back pressure.
How do I maintain Westwood muffler spark arrestors?
Inspect spark arrestor screens annually, remove carbon deposits using wire brush, ensure screen integrity without holes, and replace if damaged. Clogged arrestors reduce engine power; missing screens create fire hazards in dry conditions.
When should Westwood mufflers be replaced?
Replace mufflers showing rust perforation, cracked welds, damaged mounting flanges, or significantly increased noise levels. Failed mufflers risk burns from exposed hot surfaces and may fail emissions or noise regulations.
Why is my Westwood muffler glowing red?
Red-glowing mufflers indicate lean fuel mixture from air leaks or carburetor issues causing overheating, restricted exhaust from carbon buildup, or engine overloading from dull blades or excessive load. Address immediately preventing fire risks.
Can I run my Westwood without a muffler?
Operating without mufflers creates excessive noise violating regulations, risks burns from exposed exhaust ports, potentially damages valve seats from lack of backpressure, and may affect engine tuning. Always maintain proper exhaust systems.
