    Planning on getting Magnaflows put on my 2000 5.3L. I am trying to decide between single in single out or single in dual out. Thanks for the help

    It is a single cat system. I had a flowmaster 40 single in dual out but I am looking to get it a little quieter. The flowmaster sound great but I can barely hear my kids in the back seat which isn't bad all the time.
