hey. ive got an 03 f150 5.4l v8, and am planning to pull out the cats as part of my future exhaust setup. i'm wondering if they'll fit an 00 f250 v10. the reason being is that my friends' cats went out on his 250, and he hates the sound of driving w/o them.

 

i'm not exactly sure, but it probably could work, I'm not too sure if the V10 has bigger cats than the V8 engines and if the smaller V8 cats wouldn't flow right and not exit & flow properly, but definatly ditch the pre-cats.
