RE: Problem exhaust drone: Solution 1/4 wave, or Helmholtz resonator?
Just make sure it's not the exhaust vibrating against something that's causing the drone.
Read a whole topic on these resonators on some porsche forum out of interest, and in the end
after much faffing about with resonators the problem turned out to be the exhaust mounting.
