Husqvarna used different exhaust configurations across production years and markets. Therefore, compare the reference number, mounting points, outlet position and exterior shape with the original muffler before ordering.
When should the muffler be replaced?
A damaged muffler can cause excessive exhaust noise, visible soot around the cylinder, loose internal components or hot gases escaping towards neighbouring plastic parts. Cracks around the mounting points can also prevent the muffler from remaining tight during operation.
This Husqvarna 55 muffler restores a secure exhaust path when installed on the correct model. It is a Winzor aftermarket component and is not represented as a genuine Husqvarna part.
Clean the cylinder exhaust port before installation. However, prevent loosened carbon from entering the cylinder. Tighten the fasteners evenly and recheck them after the first operating cycles, once the engine has cooled completely.
