Abstract
A vehicle comprising: an internal combustion engine having a cylinder and an exhaust manifold for collecting exhaust gases expelled from the cylinder; an exhaust system configured to channel exhaust gases along a flow path from the exhaust manifold to an exhaust outlet, the exhaust system comprising an exhaust component configured to cause 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.
