You poor people - still using imperial measurements! In Australia we went metric over 30 years ago so don't have these type of issues!
Anyway regarding exhaust component life spans, probably the least important factor is the distance traveled. More importantly factors such as the ph of the road surface water and the distance traveled on average per trip. In Australia a petrol vehicle exhaust system typically last about 150k km whilst a diesel may last about 250k km. I live in an area where my minimum trip is about 100km and have found that my diesel exhaust lasts about 500k km. regards, Daniel Australia I too checked conversion tables and found it was not listed, so presumed the same. In any case it still seems that US exhausts last much longer than ULK counterparts. Now, just to confuse, what's a Irish mile?
