Got an 01 4x4 with a 5.4, screw. Stuck shorties on after manifolds were leaking, now looking at lt's, what do i have to do to swap to lt's. Tried searching, couldn't find a whole lot of info. any pointers would be great. Thanks!

 

Have to do some exhaust work to get them to fit, and either delete the cats or swap in some hi-flows. LT headers eat stockers for breakfast.

 

^ HA!

Very true though...
