ABSTRACT:
An exhaust device for an internal combustion engine with an exhaust pipe having a two pipe structure arranged such that the outer pipe and the inner pipe touch each other, the inner pipe being divided into first and second inner pipe sections at a location along the length of the inner pipe. The first and second inner pipes are arranged so that their facing ends are separated, in order to absorb shifts caused by thermal expansion of the pipe. The ends of both the outer pipe and the inner pipe are affixed together. The outer pipe may also be divided into first and second outer pipe sections at a location along the length of the outer pipe. The first and second outer pipe sections are joined in a telescopic joint.
