Zusammenfassung:	An engine exhaust filter system (100, 200) comprises a housing (102, 202) an d a pleated filter element (114, 214). The housing includes an inlet (109, 209 ) and an outlet (110, 210) and defines an exhaust gas flow path between the inlet and the outlet. The pleated filter element (114, 214) is disposed in t he exhaust gas flow path, and includes a filter medium (115, 215) and at least first perforated filter support member (116, 216). The filter medium (115, 215) is disposed adjacent to the first perforated filter support member (116 , 216), and includes a portion that extends beyond the first perforated filter support member (116, 216). The extended portion of the filter medium (115, 215) includes a seal that prevents or reduces exhaust gas bypass of the filt er element (114, 214). The engine exhaust filter system (100, 200) may also comprise a compression assembly (130, 230) which is operatively associated with the exhaust gas flow path and compresses the extended portion of the filter medium (115, 215) to form a seal.
