Care & Installation

Muffler or exhaust component. Let the engine and exhaust system cool completely before servicing — exhaust components stay hot well after shutdown. Inspect the gasket and mounting hardware for a tight, leak-free seal; a loose exhaust joint is both a noise and a heat-risk issue.
