I would replace the UP with a catless. It shouldnt have any effect on your emissions, but definitely gives you some safety about not worrrying about having your cat break up and mess your turbo. They got rid of the cat in the UP for 2006 and on I believe.

As for the DP I went performace so, I dont know if anyone makes an OEM replacement.
