It's a drumless version of the 28th bgm from the 1st Naruto Shippūden Original Soundtrack called Hurricane Suite (疾風組曲, Shippū Kumikyoku). This bgm is 10 minutes long, the part used for this episode is the 2nd one but unfortunately the drumless version has never been released, you can find a good ripped version from the anime on YouTube by searching for: "Naruto Shippuuden Unreleased Soundtrack Hurricane Suite (Part 2) (almost drumless)"
