change the 02 sensores.

if that does not "work" change the cat.

when you change a cat it is a good idea to change the 02 sensors any way.........

Answer the damn question.

Get an OEM cat.

It is NOT the header.

There is Bosche oxygen sensor at pep boys but I don't think they make it for Mitsubishi. just try or ask Pep Boys and skip Autozone cheap products.

the prices vary by the way mine was $150.00 for a 99 mirage yours must be a little more expensive. but you can also buy them on line and you have to wait. make sure the vin and engine number are correct.

There is no 'e' on the end of Bosch. Anyways, they SUCK.

I don't know how much the stock cat goes for on that car.

High flow cats are a crock of **** too. A test pipe is just a piece of metal pipe to go in place of the cat. This will keep the check engine light on.
