Abstract: Systems and methods are provided for a combined spark arrestor and muffler assembly. In one example, a system may include a combined housing, the combined housing including a spark arrestor portion including a plurality of stator fins, and a muffler portion including acoustic packing, the muffler portion fluidically coupled to the spark arrestor portion via a first sliding joint and a second sliding joint. In this way, a single component of a vehicle exhaust system may reduce sparks and/or carbon deposits in exhaust gas, while also reducing exhaust noise.

Abstract: A thermal expansion/pressure compensator includes a body having an inlet at a first connection point and an outlet at a second connection point. The body includes a flexible member extending along a portion of the body. The body has an internal chamber configured to receive a fluid via the inlet. The internal chamber is shaped to direct fluid through the flexible member and out of the body via the outlet. The flexible member is configured to flex responsive to expansion of the body. The compensator also includes a rigid member operably coupled with the body. The rigid member is thermally and fluidly isolated from the body and the flexible member. The body, the flexible member, and the rigid member are formed as a unitary structure.
