Zusammenfassung:A vehicle comprising: an internal combustion engine having at least one cylinder, the internal combustion engine comprising an exhaust manifold for collecting exhaust gases expelled from the at least one cylinder; an exhaust system configured to channel exhaust gases along a flow path from the exhaust manifold to at least one exhaust outlet, the exhaust system comprising at least one exhaust component configured to act on exhaust gases flowing though the exhaust component and causing an alteration to engine-generated sound pulses passing through the exhaust component; and a sound bypass device comprising a sound inlet port at a first location on the exhaust system before a first exhaust component along the flow path and a sound outlet port at a second location on the exhaust system after the first exhaust component along the flow path, the sound bypass device being configured to transmit engine-generated sound pulses from the sound inlet port to the sound outlet port whilst preventing flow of exhaust gases from the sound inlet port to the sound outlet port.
