ABSTRACT:
An assembly for fitting together multiple exhaust pipes in a multi-cylinder engine into a single unit is provided. The assembly includes a cap and a choke pipe connected to the cap. The cap includes a surface with multiple sockets protruding from the surface in a direction opposite to the choke pipe whereby the sockets engage the exhaust pipes. The cap also includes a skirt, which surrounds a perimeter of the surface. The skirt extends from the surface in a direction toward the choke pipe. An internal surface of the sockets, an internal surface of the skirt and an internal surface of the choke pipe are linearly arranged with respect to each other.
