I bought the: Magnaflow Catalytic Converters - 49 State Legal Universal Fit Part #: 99209HM Had them installed for $150. They replaced the original ones on the truck with a stock exhaust (6.0 GMC). They seem to make the exhaust sound a little deeper in tone, which I like.

A friend of mine liked my MBRP system on my truck so much that he had me get him a kit for himself that we put on and it looks great and sounds just as good! Gives you a nice deep tone without all the drone in the cab.
