Cost of catalytic converter
I have a E60 M5,
last time I check out the whole catalytic converter system, it was quite pricey,and since I love to push my car from time to time and I am planning to own this car long term, I am afraid the catalytic converter will age prematurely from the high heat of the exhaust, should I :
1. purchase warranty for the catalytic converter?
2. ask a shop to make a bolt on section for test pipe or interchange with catalytic converter from other "more universal" part?
so I can always have brand new CAT when it comes to time for smog test?
