ABSTRACT:
A pair of front exhaust pipes are joined to a rear exhaust pipe by an exhaust pipe joint. The front exhaust pipes have downstream end portions projecting into the exhaust pipe joint so that between the outer walls of the downstream end portions and the inner walls of the exhaust pipe joint there are formed annular spaces for receiving reflected waves travelling in the upstream direction and limiting the propagation of the reflected waves into the downstream ends of the front exhaust pipes.
