Abstract
An exhaust system for a vehicle includes a muffler including end walls and a side wall connected to the end walls enclosing an interior space of the muffler. A first pipe is disposed within the interior space of the muffler and extends from one end of the muffler at which exhaust gas enters the muffler. A catalyst is located in the first pipe and at least one additional pipe is disposed within the interior space such that a longitudinal axis of the at least one additional pipe is spaced from a longitudinal axis of the first pipe in a direction that is substantially perpendicular to the longitudinal axis of the first pipe. The first pipe includes a plurality of holes disposed in a sidewall thereof at an upstream side of the catalyst in a direction in which exhaust gas passes through the muffler. The holes in the first pipe are arranged such that some of the exhaust gas passes through the catalyst and the remainder of the exhaust gas passes through the plurality of holes so as to bypass the catalyst.
