Key Features

• Genuine OEM Exhaust Specification — Manufactured to the same material grade and back-pressure tolerance as the original muffler assembly, ensuring proper exhaust flow and engine performance.
• Complete Kit Included — Supplied as a full muffler and flex kit assembly, so the muffler body and flexible exhaust connector are replaced together for a complete, lasting repair.
• Broad Saw Compatibility — Fits SP, PS, and CS series pavement and flat saws across multiple blade-size configurations, from 16-inch through 36-inch cut models.
• Direct Drop-In Replacement — Engineered to match original mounting points and connection geometry, making installation straightforward without custom fitting or modification.
• Protects Engine from Exhaust Back-Pressure Damage — A cracked, corroded, or missing muffler assembly disrupts exhaust scavenging, leading to power loss and potential engine overheating on long cutting runs.
• Operator Safety Compliance — A properly sealed muffler and flex assembly contains hot exhaust gases away from the operator and fuel system, reducing burn and fire risk during operation.

The muffler and flex kit assembly manages exhaust gas flow out of the engine after combustion. The muffler dampens exhaust noise and controls back-pressure to keep the engine running efficiently, while the flexible connector section absorbs vibration between the engine and the rigid exhaust path — preventing stress cracks caused by the constant vibration a pavement saw produces during cutting. When either component fails, the result is increased exhaust noise, reduced engine output, and the risk of hot gas escaping near the operator or fuel lines. Replacing the full assembly together restores the exhaust system to its intended function and extends the service life of surrounding components.
