A tune is not at all required for an aftermarket exhaust system. A tune however MAY free up a little extra horsepower when paired with a lighter, more freeflowing aftermarket exhaust.
What you are thinking of is probably an aftermarket downpipe, that is when a tune would be necessary to rid of the CEL.
