Abstract:
An exhaust device of a six-cylinder engine includes first to sixth cylinders and a manifold extending from the first to sixth cylinders. The first to sixth cylinders are ignited in that order. The exhaust manifold can include first to sixth upstream exhaust pipes extending respectively from the first to sixth cylinders, first to third midway exhaust pipes extending respectively from a joined portion of extended ends of the first and fourth upstream exhaust pipes, a joined portion of extended ends of the second and fifth upstream exhaust pipes, and a joined portion of extended ends of the third and sixth upstream exhaust pipes, and a downstream exhaust pipe connecting extended ends of the first to third midway exhaust pipes to the ambient atmosphere.
