A heating apparatus for an exhaust gas system, the heating apparatus comprising:

• a container body defining an exhaust gas pathway;
• a heater flange component attached to an exterior of the container body, wherein the heater flange component and the container body define corresponding mating portions therebetween, the mating portions connecting the heater flange component to the container body;
• a heater assembly disposed in the exhaust gas pathway and secured to the heater flange component, the heater assembly including:
• at least one heater element;
• a bracket assembly that secures the at least one heater element in the container body;
• and
• a conformal bracket for securing the at least one heater element to the bracket assembly;
• a junction box mounted on the heater flange component, the junction box including one or more electrical terminals that connect the at least one heater element to a power source;
• and
• a perforated box assembly disposed between the heater flange component and the junction box to allow for air cooling of the junction box, wherein the perforated box assembly includes one or more side walls that have a plurality of holes defined therethrough, and the at least one heater element extends through the perforated box assembly to connect to the one or more electrical terminals.
