Most cars come with stainless exhausts now - and those that don't -
put them on at first replacement. My first Aerostar exhaust went at
about 30 months - the replacement stainless lasted untill the guy I
sold it to scrapped it at 300,000km, about 15 years or so later.


The removal of lead from Gasoline helped both oil life and exhaust
system life. Plus, a hot catalytic converter upstream helps also.
