i have an 02 f150 and am planning on cutting out the 4 original cats and putting on 2 high flow mags. the part number on the cats is 94006. will i lose or gain any power? i have a di/do flowmaster super 40 muffler. i just want to make sure that my mileage will get better and that the power will not decrease. also how will the sound change. thanks
youl get better power throught the rpm range and wont hurt your mpg's and youl gain alot of sound

yeah they mainly will give you alot more noise, why i got them haha. but in all honesty, the chances of you actually FEELING a big difference in hp/torque is very slim. haha. most do it for the sound. it was a good upgrade i think, worth the money. made my super44 sound sweet

Doing this mod with your setup will more than likely just make it louder and introduce "crackling" and backfiring with an aggressive fuel pedal.
I wouldn't expect too much power wise, but throttle response should be a tad quicker. I had a similar setup on a 95 and liked the aggressiveness, but the crackling when the engine was cold was a bit annoying. I now prefer smoother deeper tones, But some guys still like that stock car sound.
