Which silencer is the quietest, FMF Megamax, Power Core IV, WB E-Series, or Supertrapp 4" Racing Series?

Thanks

For what model of quad?

The mufflers you list are all about the same dB level -- probably close to 97 - 98 dB on a 300EX (for comparison, the stocker comes in at about 82 dB).

This can vary for different models -- those same systems on an ATC 350X would be another 3-4 dB louder.

None of them would be considered "quiet". There's only one "quiet" aftermarket system that I know of, the Supertrapp EAR.
