Abstract:
A Y-pipe assembly for attachment to the respective ends of a pair of primary exhaust pipes or header assemblies which lead exhaust gasses from the engine of a motor vehicle, and to the inlet of a boom tube exhaust pipe which mounts to the bottom portion of the frame or chassis of the motor vehicle, which Y-pipe assembly and boom tube exhaust pipe provide improved ground clearance, comprising:a first secondary exhaust pipe of a generally rounded cross-section comprising an inlet portion connectable to one of the header assemblies for receiving exhaust gasses therefrom and a longitudinally beveled outlet portion; a second secondary exhaust pipe of a generally rounded cross-section comprising an inlet portion connectable to the other of the header assemblies for receiving exhaust gasses therefrom and a longitudinally beveled outlet portion; and wherein said beveled outlet portions of said secondary exhaust pipes are affixed together along a respective edge of each thereof so as to merge together with respective centerlines thereof at an oblique angle to a single outlet opening which is connectable to the inlet of the boom tube by affixing thereto, and wherein said secondary exhaust pipes are substantially the same length as measured along said respective longitudinal centerlines thereof.
