Abstract
An exhaust manifold for an engine has sets of branches tuned to the fundamental frequency of exhaust products but with the branch length of the sets different so that the engine speed at which resonance occurs in each set is different. An inlet manifold has runner sets with each set being paired with an exhaust manifold branch set serving the same cylinders and tuned to effect resonance of combustion air in the runners at the same engine speed that resonance occurs in its associated exhaust branches.
