This invention is a new and improved muffler for use on the exhaust of noise producing machines such as automotive engines, and the like. It is particularly characterized by utilization of a single inlet into a chamber from which there are a multiplicity of louvered or otherwise appropriately configured exhaust tubes appropriately wrapped with noise entrapping material, and in a preferred form utilizing a ceramic fiber material, and wherein the multiplicity of tubes ultimately open into a chamber from which the ultimate outlet is ducted.
