Exhaust system assembly

摘要

An exhaust system (10) includes first (12) and second (32) exhaust pipes each of which has an upstream end (16,36) communicating with an engine and a downstream end. The exhaust pipes (12,32) are of different lengths. A length equalizer (52) includes an outer pipe (54) and an inner pipe disposed within the outer pipe. One end of the inner pipe communicates with a space between the inner and outer pipes. The longer (12) of the two exhaust pipes communicates with the space between the inner and outer pipes of the length equalizer. The shorter (32) of the two exhaust pipes communicates directly with the inner pipe of the length equalizer (54). The distance between the downstream end (30) of the longer exhaust pipe (12) and the inner end (50) of the inner pipe of the length equalizer (54) is substantially equal to the difference in length between the longer (12) and shorter (32) exhaust pipes.
