Description: A brand new muffler for CT series Stover engines.  Muffler has 1.25 inch NPT threads.  Will fit lots of other engines as well and works great on many models.  Measures 7inches across 4 inches thick.  A really nice muffler and super nice quality! Please check your thread size before ordering. I have this same muffler availible in several other thread sizes if you need something other than 1.25inch.
