You drive it to the local exhaust shop and have them do it. You are not equipped for exhaust work as most shops aren't.

Loosen the pipe from below. Remove the bolts that fasten the heat shields to the exhaust manifolds, position the shields aside as to access the upper 2 nuts and remove. The converters drop out of the bottom. If you need procedure and or illustrations, reply to this post.
