I was recommended to Mesa Muffler by Highland Auto for a catalytic converter due to failed emissions. (I've never had a car fail before, but have wondered why some passed.) I called Mesa Muffler for a next-day appointment, and was "in and out" just as promised. I love people who respect my time! I didn't price shop - knowing a lower price elsewhere usually results in: and, and, and.... What's that saying again? Oh yeah, "fool me once..." A discount is offered for paying cash.
