The housing includes an outer peripheral wall disposed about a central axis and defining an interior hollow space configured to receive exhaust gas from an exhaust pipe of the exhaust system such that the exhaust gas flows through the interior hollow space. The heating element is positioned within the hollow space and including a first end and a second end. The heating element forms a zig-zag shape extending in a radial direction relative to the central axis.
