Abstract

An exhaust system for the internal combustion engine of a snowmobile that permits joining of the exhaust ports of pairs of cylinders and the use of a single silencer without having the exhaust pulses from one cylinder adversely effect those of another cylinder of the joining pairs. This is done by having adjacent cylinders fire at 180 degrees from each other so that their exhaust gases can be combined in a single manifold without adverse effects. The individual exhaust manifolds of the paired cylinders then communicate with a common silencing device through separate inlets.
