I have a 01 King Ranch and im trying to find the right exhaust. I've had no muffler to glass packs, to the pypes violator and a bunch of other stuff.....Currently i have the factory system but instead of the muffler i replaced it with just pipe.....I would like to know what you guys think of taking out the 4 cats and replacing them with 2 high flow flowmaster cats, then have them go to a flowmaster super 10 series muffler with a single inlet and dual outlet where the tips come out behind the rear tires??....What do you guys think? i want it to really roar but still have a nice tone....are there any cats flowmaster makes that are better for performance vs. sound? or any other company? Any advice would really help....and i dont want to shy away from sound, i drove around with no muffler and the pipe coming out underneath the passenger seat for 3 months. Thanks

also i have the 5.4, 4wd
