What factors influence the temperature of a car's exhaust?
The biggest factor is the engine. Cooling, combustion and other issues will increase the amount of heat generated. How the vehicle is being used is another factor. Higher engine RPMs will produce more exhaust flow and thus more heat, as will driving the vehicle for long periods. The final major factor is the pipe design. Pipes that have lots of bends, especially tight bends, will get hotter because this traps exhaust gas longer.
What maintenance steps or modifications can optimize the overall performance and longevity of a Lincoln MKC?
You should always follow the maintenance schedule recommended by the manufacturer. This includes oil and air filter changes, fluid checks, tune-ups, tire changes and other routine maintenance. Neglecting these tasks will make the vehicle more likely to break down or perform sluggishly. Two Lincoln MKC modifications that will help performance are an aftermarket exhaust system that gives you a performance sound like the Sport Touring Axle Back.
