    So, i've been trying to figoure out why the RAB has been so shatty on mpgs. I know its a 4x4, blabh lbah blah. But it should be no where near as bad as it is. Will clogged cats cause the mpgs to suffer? I know my mechanic tyolsdm me the fuel filter wa spretty much clogged since it looke dlike the original one from 97. Any thoughts/input?

    Our local maxi muffler shop has a great manager, he will backpressure test our exhaust systems to check for clogged cats at no charge.

    clogged cats are pretty common on a 14 year old truck. i think replacing them with OE cats or even 2 hi flow cats would get you some better mileage
