catalytic converter ?

hey. i'm planning on pulling out my cats for my exhaust system. i have an 03 f150, 5.4 l v8. I was wondering if they will fit a 2000 f250 v10. my friend's cats on his 250 need to be replaced, and i am wondering if mine would fit.

did you know that you can buy a high performance converter, check out the parts on the internet

Unfortunetely you can not swap cats for several reasons. The main reason is the restriction requirements for a v8 are different than a v10. The Cats on a v10 are bigger than a v8 which means he would probably kill his engine with too much back preasure.
