Abstract
An exhaust system features first and second exhaust conduits fluidly coupled to first and second cylinder banks of an associated internal combustion engine. The first and second conduits cross over each other downstream of the engine and are coupled together by a common chamber. The common chamber allows pressure pulses in the first and second conduits flowing past the chamber in opposite directions to at least partially cancel each other, thereby reducing low frequency exhaust noise.
