I tried the Donnie FL Yokozuna and the Donnie FL koi they both quieted the gun down to 105 DB. I went with the koi because it was $100 cheaper but I'd like to get below 100 decibels can anybody recommend a moderator that would do that for me? I know you can add to the Yokozuna but I think it's already too long the way it comes from the factory I'd rather not go any longer than the koi that I have. Thanks in advance
