Patent ID: 8181732

Claim:
A Y-pipe exhaust crossover which leads exhaust gasses from an engine of a motor vehicle to the inlets of a pair of tail pipes which mount to the bottom portion of the frame or chassis of the motor vehicle, comprising: a) a Y-pipe assembly for attachment to the respective ends of a pair of primary exhaust pipes or header assemblies, the Y-pipe further comprising: i) 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; ii) 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 iii) 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 of a generally flattened oval cross-section; and b) a Y-pipe splitter attached to the single outlet opening of the Y-pipe assembly and adapted for attachment to an inlet of each of the pair of tail pipes, the Y-pipe splitter further comprising: i) a first splitter tail pipe section comprising a longitudinally beveled inlet portion connectable to an outlet of the Y-pipe assembly for receiving exhaust gasses therefrom and outlet portion connectable to one of the tail pipes; ii) a second splitter tail pipe section comprising a longitudinally beveled inlet portion connectable to an outlet of the Y-pipe assembly for receiving exhaust gasses therefrom and outlet portion connectable to one of the tail pipes; and iii) wherein said beveled inlet portions of said splitter tail pipe sections 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 inlet opening of a generally flattened oval cross-section substantially matching the flattened oval cross-section of the single outlet of the Y-pipe assembly, and said single inlet opening of the Y-pipe splitter is affixed directly to the single outlet opening of the Y-pipe assembly to create a flow path for exhaust gases from the inlet portions of the first and second secondary exhaust pipes of the Y-pipe assembly to the single outlet opening of the Y-pipe assembly directly into the single inlet opening of the Y-pipe splitter and to the outlet portions of the Y-pipe splitter.
