...on my 1991 300D 2.5. It turned out to be one of the connections for the crossover pipe which was not tightened properly. The gap allowed just enough air to escape to produce that incredible sound. Once i tightened all the bolts on the crossover pipe, the sound went away. I believe there is a gasket at the joints to help seal the system. Fortunately, tightening alone fixed my problem.

Hope this helps.
