QUESTION: The year and Model is a 2001 Toyota Tundra with 120,000 miles and the mechanic is an authorized toyota dealer.  Thanks for responding

Answer
There is a recall for exhaust manifolds for a noise issue, there is no mileage or time limit, the mechanic can not charge you for diagnosing the exhaust system since it's covered by the recall, the dealer is re imbursed by Toyota for the claim. In most states if not all, it is illegal to charge a customer diagnostic fees if the repair is covered under warranty.
