Abstract
A setting tool for actuating a downhole plug in a wellbore includes a housing, a piston positioned at least partially within the housing wherein the piston defines an internal firing chamber that is in fluid communication with an exhaust port, an expansion chamber positioned between an outer surface of the piston and an inner surface of the housing wherein the exhaust port is configured to convey combustion products along a combustion flowpath extending from the firing chamber and into the expansion chamber, and an exhaust diffuser distinct from the piston and the housing and including an exhaust passage and at least one baffle face, the baffle face configured to redirect the flow of combustion products along the combustion flowpath and channel the flow of combustion products into the exhaust passage.
