I have an 04 FX4 that looks just like your from what I can see(super cool truck by the way) and i am looking at going to true duals. I have a stock muffler that looks like a stick of pulpwood hanging under there, it will go for flow masters. The question is did you have any issues with getting your duals by the spare tire?
Thanks.
