Check Engine Light

[ROX]

Thanks! I forgot to mention that I already have a Flowmaster exhaust.

They told me they would only replace the cat with the problem. That means one new and one with 50k miles on it.

One other question: If you're adding an aftermarket exhaust system, wouldn't you want to add high flow catalytic converters as well? Otherwise, you'd have one little link in a big chain.???
