   Re: Mortgage Asset-Backed Pass-Through Certificates, Series 2007-SP1

Ladies and Gentlemen:

     We have advised Residential Asset Mortgage Products, Inc. (the
"Registrant") with respect to certain federal income tax aspects of the issuance
of the Mortgage Asset-Backed Pass-Through Certificates, Series 2007-SP1 (the
"Certificates"), which will be issued pursuant to a Pooling and Servicing
Agreement, dated as of March 1, 2007, as more particularly described in the
prospectus, dated December 4, 2006 (the "Base Prospectus"), and the prospectus
supplement, dated April 5, 2007 (the "Prospectus Supplement" and, together with
the Base Prospectus, the "Prospectus"), relating to such series, each forming a
part of the Registration Statement on Form S-3 (File No. 333-131211) as filed by
the Registrant with the Securities and Exchange Commission (the "Commission")
under the Securities Act of 1933, as amended (the "Act"), on January 20, 2006,
and declared effective on March 31, 2006 (the "Registration Statement").
Capitalized terms used but not defined herein have the meanings specified in the
Prospectus.

     The description of selected federal income tax consequences to holders of
the Certificates that appears under the heading "Material Federal Income Tax
Consequences" in the Base Prospectus and in the Prospectus Supplement does not
purport to discuss all possible income tax ramifications of the proposed
issuance, but with respect to those tax consequences which are discussed, in our
opinion such description is accurate in all material respects to the extent it
relates to matters of law or legal conclusions with respect thereto. In
addition, we adopt and confirm the statements in the description identified as
the opinion of special United States federal tax counsel.
