02 5.4 exhaust
I have a 2002 f-150 5.4 4x4. It is completely stock other than tires/wheels. I have had a single in dual out flow on it. Now i just cut it out and have the cats and a y pipe into duals. It sounds ok but i want something louder/deeper. What would be the best thing for me to do. Can i run true duals? remove cats? what about the 02 sensors ? i would like to run no cats or gutted cats and a flowmaster. What would be my best bet?

Cut out the 4 stock cats and add high flow magnaflow cats. You can place one high flow cat on each side of the Y-Pipe between the O2 sensors. The high flow cats will not trip your check engine light and it will give you a deeper, more aggressive sound with your Flowmaster. The cats will also free up 5-8 rwhp.
