Dave is right... Just clean the headers and if there are no holes from rust through, just re-install to the new mufflers. There are two carbon sleeves that should be inside the muffler inlet pipes. Visually inspect them for breaks or damage.. Replace if damaged. I've only been able to get them at the Honda dealer.
Rusted exhaust pipes are common on any type of vehicle and it's basic cause is from heating and cooling of the metal exposed to the atmosphere. As the metal cools, moisture in the air condenses on it and rust begins. It continues as long as the metal is exposed.. Chroming helps a lot, but once the chrome either burns or wears off, it's all over..
Don't hesitate using the old headers. They'll last a very long time...
