We have a 2008 Georgetown on and 22,000 GVWR Ford F-53 chassis. While climbing a hill somewhere in Arkansas, we heard a bang and then a rattling noise. First thought, there goes the engine! We still had plenty of power. We pulled into a closed gas station, I revved up the engine and it sounded OK. When the engine was returning to idle, I could hear the Cat rattling.
I have the Banks Power Pack, and its been on it since 2013 and 20,000 miles. Of course its out of the emission warranty by 1 year.
Anyone else had an issue like this?
