I posted a SPL comparison of a stock vs. Prodrive ovaltip axle back a while ago in the Car Parts Review forum (I think). It is a complete and thorough test including ambient, stock and Prodrive levels all broken down into octaves (although not necessary). If you search, I'm sure you could find it, and of course, the info is all yours for the taking!
