1. An exhaust control system for a vehicle, comprising:

  • an exhaust system modeling module that estimates an input gas temperature, an output gas temperature, a mass temperature, and a pressure for an exhaust system component of an exhaust system implemented in said vehicle, wherein exhaust gas flows through said exhaust system component; and

    an actuator control module that selectively adjusts an engine operating parameter based on at least one of said input gas temperature, said output gas temperature, said mass temperature, and said pressure.
