I got a new DV fitted the other week, it works fine when changein at 3-4k revs, anything higher and theres a strange noise, heres a vid of it YouTube - Dump Valve
hard to tell on your vid, it sounds as it should, make sure you have all the pipes connected properly other than that without hearing it in the flesh so to speak it sounds fine
