The intention is to allow the outer shell many more years of life than an aluminum metal shell. A shell made of a weaker metal could easily fail due to exposure from adverse weather conditions. Weaker metals are vulnerable to deterioration and can cause exhaust leaks that would directly effect the purpose of the catalytic converter. Because of their exterior design, the internal components of a converter are more vulnerable than the exterior. The interior and exterior design of a catalytic converter has many elements that can preserve its intended longevity. While an average lifespan of seven to 10 years–depending on the elements and condition of the vehicle–are common for most original converters, aftermarket converters usually only survive for half that amount of time due to inferior construction.
