This listing is for a muffler.  It was removed from a model #DB8621SH Powersmart 21 inch self propelled mower with a OHV 209cc horizontal shaft engine.  It is in good condition.  It may fit other models as well.  Please confirm that this part will fit your mower before purchase.  Payment within 2 days of purchase.  I will combine shipping on multiple purchases when possible.  If you are looking for a part that I don't have listed please ask, I might have one.  Thanks for looking!
