Abstract

PURPOSE:To increase a bank angle, by a method wherein the openings on the downstream side of a plurality of exhaust pipes collected to an expansion chamber are formed in a vertically long square, and are positioned in juxtaposition to each other in a state that the right and left sides thereof are adhered to each other. CONSTITUTION:A plurality of exhaust pipes 44a and 44d are collected to an expansion chamber 18 disposed below an engine. The openings on the downstream side of the exhaust pipes 44a and 44d are formed in a vertically long square and are positioned in juxtaposition to each other in the direction of the width of a car body in a state that the right and left sides thereof are adhered together, and are held in a manner to enter the expansion chamber 18. This constitution enables decrease of the lateral width of the expansion chamber, resulting in the possibility to increase a bank angle.
