The Thinline Linear Muffler has a new patent-pending design.
A bypass cavity handles water that’s not required for exhaust cooling, and it’s discharged through a molded, contoured diverter to avoid back-pressure problems. In addition to operating quietly, it simplifies installation and leaves more space in the engine room, the manufacturer says. $4,000 to $9,000, depending on engine size and configuration.
