What would be a reasonable charge to have a new exhaust on a Corsa car?

denise t questioned:

Anyone any thought what I would be probable to pay for a new exhaust on a Corsa 1.2 car. The car is 8 being ancient and in excellent condition but I was warned it may need a new exhaust logic in its next MOT, anyone out here know what would be a evenhanded payment to have one en suite, be grateful you.
