My '98 Honda Accord EXL 4 cyl needing a catalytic converter. 113000 miles of
mostly highway driving - check engine light came on so i took it ot the
dealer. The dealer said it needs a catalytic converter. And that they want
$800 for the Honda model, which i think is way too much.

Can i do any damage to the vehicle running it until i can get a cat
converter on it, and is anything wrong with not using the honda dealer
official replacement.

thanks
