  • Double layered, bent exhaust pipe
    Patent number: 10174663
    Abstract: An exhaust pathway for an internal combustion engine passes from a larger pipe to a smaller pipe, and then back to a larger pipe. The smaller pipe has a bend of at least approximately 80°, and each of the smaller and downstream larger pipes is disposed within, and spaced apart from, portions of a shell, such that cooling air passes in an air gap between the pipes and the shell.
