A connection between an expansion chamber outlet and a rubber cuff that accommodates an inlet portion of a throttle body exhibits an overmolded, hot plate or spin weld type of connection between an expansion chamber wall outlet portion and the rubber cuff. The rubber cuff may have a bellow in it to absorb shock and force from the throttle body. The rubber cuff may be insert molded around the expansion chamber outlet such that the joined interface between the rubber cuff and the expansion chamber is from the molding. The molded interface prevents separation due to air forces through the chamber and cuff. A cuff recession on a cuff inside diameter receives a protuberance of the throttle body inlet portion. A band clamp fits around the outside diameter of the cuff, adjacent the throttle body inlet protuberance, to prevent movement relative to the throttle body.
