can you take a cat converter off 03 4.8?
yes.. just need to get the rear 02's deleted in your tune or get 02 sims..if you dont you will have a service engine soon light..
from what ive heard the truck will not even run right with them off. cause when i got my straight pipes i told them to take them off but he said it would not run right.
get a tune, then u can do almost anything u want with it. :hshake:
could i take the out w/ a superchips programmer or any other kind?

No you need to have the o2 sensors deleted from your ecm, a "custom tune".
Allen Nelson is the shit from what i have been told. :thumb:

He deleted the cats from a buddy of mine's truck with a custom tune "2500hd6.0" and it runs like a scalded ape!!!
you can only delete the rear o2 sensors from what i understand the first ( close to the engine) can not be deleted as the engine needs these 2 to run..
