Wei, I have had a few different non-Exchange hosted SPAM solutions inserting mail into my Exchange 200x environment and never has Exchange stripped any x-maybe-spam type headers that are put in by another MTA. There may be an application that is doing it that is running on your Exchange 200x servers (or handing off the mail to your servers), but the Exchange servers them selves do not remove X-headers. What kinds of software do you have loaded on your Exchange servers and how is your mail routing between the Internet, your 5.5 environment, and your 2003 environment?
