Catalytic converter question X6M
Long story short.....
I'm located in Costa Rica, ALL gasoline sold here comes from a government agency ( better called a monopoly) a couple of weeks ago they gave us the "good news" that they found a harmful aditive called MMT on the gasoline they have been buying since early 2012, it seems to be pretty bad on catalytic converters, many cars are starting to get the check engine light on, many others need to have the catalytic converters replaced.........so my question goes, if there is a good aftermarket (cheaper than OEM) for my X6M just in case I will need a replacement soon ? (hope not)
Any feedback will be appreciated
