Silencer unit + gasket set for STIHL MS660 MS650 066 petrol chainsaws

Is your large-displacement STIHL chainsaw unusually loud, experiencing a noticeable loss of power, or emitting black smoke or exhaust fumes from the muffler? This is likely due to muffler corrosion, damage to the internal baffles, or worn seals. This high-quality muffler with matching seals is specifically designed for large chainsaws like the STIHL 066, MS660, and MS650 and restores the proper functioning of the exhaust system. Muffler functions: Noise reduction: Thanks to its multi-chamber internal structure, it absorbs the energy of exhaust pulsations, significantly reducing noise. Performance increase: The muffler's internal volume and design directly influence exhaust back pressure and thus engine performance. Safety: It channels hot exhaust gases away from the machine, preventing burns and fires. Exhaust filtration (with spark arrestor): It captures sparks present in the exhaust, reducing the risk of fire. Key Features: Perfect Fit to the Original Exhaust Port: The shape of the silencer's connection surface on the cylinder and the spacing of the mounting holes conform to the original specifications. This ensures perfect alignment with the exhaust port after installation, eliminating the need for enlarging or modifying the holes. High-Temperature Resistant Coating: The silencer surface is coated with a high-temperature resistant black or silver coating, providing lasting protection against oxidation, rust, and peeling, thus preserving its pristine appearance. Reinforced Mounting Brackets: The area around the mounting holes is reinforced to prevent the mounting brackets from breaking due to vibration and to extend their service life. Precision Stamping and Welding: The body is precision stamped, and the gaskets are welded under argon shielding gas. This ensures consistent and robust welds without porosity or leakage.
