<p>A muffler for a small two-cycle engine comprises a muffler body having an expansion chamber, an exhaust gas guide member (21) for covering an exhaust gas feed port formed in the muffler body, and a cover hood (22) for covering an exhaust gas discharge port formed in the exhaust gas guide member. An attachment (20) is structured by integrating the exhaust gas guide member (21) with the cover hood (22). The attachment (20) can be so slid in relative to the muffler body that the attachment is capable of freely engaging with or disengaging from the muffler body.</p>
