Walker Catalytic Converters

    I need to replace my catalytic converters on my 2002 Suburban with a 5.3L Flex Fuel. I have located a Walker direct replacement.

    Has anyone had experience, either good or bad, with a direct fit Walker exhaust products?

    Is the efficiency of after market catalytic converters as good as OEM?

    Thanks.
