Like Roelof stated, your pipe is "Flexible" via the connections at the header and the Pipe, the Pipe Mount Wire allows you to fine tune its location. Also you can turn the header a tiny amount Anti Clockwise which may allow for a loss of 1 mm or 2 in overall length. Either way great setup, and anything Mugen and Rody is ok in my book! (Roelofs too, as he like I are Mugen guys)
