Hi flow cats and super 10?

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

I do not mean to sound rude or disrespectful, this exact question was asked within the last week or two with a whole series of replies. It is inadvisable to remove the cats due to the engine management system is setup. There is no power gain, only a noise factor to be obtained. Flowmasters seem to be the majority choice from what I've seen. But do some searching on her and see what ya come up with

Look on YouTube man. There's all sorts of F150's with Flowmasters and cats removed on there. There's a gray 01 screw on there that has all cats removed and flowmasters dumped at the rear axle. Sounds pretty good.

IF you replace the factory set up of 4 cats ( 2 each side) with 2 cats (1 each side) that are of good quality & retain the down stream O2 sensor factory placement...then you should be OK with no issues with the CEL coming on due to lean run condition. keep the pipe size either 2-1/4 -2-1/2 dia and bottom end torque loss will be minimal

as to what mufflers you wish to put on down stream from there is your choice...just be warned that flowmasters tend to drone inside the cab ....but that doesn't seem like a issue for you now...just might be a few months down the road.
