The FDM had the best sound by far and I liked the larger tips.  But, the PSE is special.  I ended up deleting the secondary cats to get some sound out of the PSEs.  No drone at all with the FDMs.   The other two being stock also had no drone.

This is what you should listen to.  Only exhaust system I can personally say has zero drone (other systems I rationalized for awhile, eventually drove me nuts with their drone) is from FD Motorsports.
