EXHAUST COMPONENT WITH LOUVER BRIDGE FOR SUPPRESSING VEHICLE EXHAUST PIPE RESONANCES AND VEHICLE EXHAUST SYSTEM WITH EXHAUST COMPONENT

摘要

An exhaust system component (18) includes a pipe having a pipe wall (12) with an inner surface defining an exhaust gas passage and with an outer surface and a louver bridge portion (18) formed in the pipe wall (12). The louver bridge portion (18) has bridge ends (21) transitioning from adjacent pipe wall portions to a bridge raised portion (19) with raised side edges (22) detached from adjacent opening side edges (20) of the pipe wall (12). Each bridge side edge (22) is radially outward of the adjacent opening side edge (20) of the pipe wall (12) to define a louver opening (30) at each of two opposite sides of the louver bridge portion (18). Fluid communication through the two louver openings (30), between the exhaust gas passage and an exterior of the component, attenuates resonant frequencies generated during operation of an exhaust system to which the exhaust system component (10) is connected.
