I recently went into Aztecas Muffler Shop with a Problem with the Catalytic Converter they had installed two years ago. I expected, as is common in today's world, an argument and (of course) to be stonewalled and denied warranty service. To my shock and surprise, Hector, the manager, not only acknowledged that the problem would be covered under warranty, but took care of the problem IMMEDIATELY at NO CHARGE. I highly recommend their professionalism and integrity. In today's Business climate, this company has an exceptional sense of honesty and honor.
