I'd treat the new pipes to a generous coating of hi temp paint on the insides so they never rust again.
Did that with my 341's eons ago and no bluing, no rusting, ...... Don't know if you can pull the baffles from the 405's or not. If not, thin the paint down so it won't plug small holes but you'd have to treat them twice.
Then tuck them away and save them.
