just got my new sniper fx impack m4 25 cal. today. put a arkin 5x25 x56 eye ball on it and went out back to give it a try. oh my first shot thought it did not shoot lol that thing is so quiet its un real, and thats the moderator that came with it. i have a aea 25 chalenger 25 with a yokozuma on it so i tried it on the fx what a joke 200 dollars for the zuma no comparison what so ever the factory one that came with the fx beats the heack out of the zuma
mouse fart quiet

I have the impact .25 cal and I can say it is not mouse fart quiet. I'm guessing you come from pb, then yeah it would be mouse fart quiet. Try shooting a marauder .22 cal. Imo the marauder is 5 times more quiet than a impact .25 cal. All you hear from a marauder is the ping sound of the hammer hitting the valve. It's just that quiet.

To the OPs point I don’t love the Yokozuna myself. I put on three extra baffles just to get it to acceptable levels on my fx drs. My .35 cal impact M3 is still a tad quieter than my .25 cal DRS. I use a Ronin and extension on my .35 cal. Those barrel shrouds do quite a bit on those FX impacts. If you look inside of them there’s porting and or baffling of some kind. Combine that with a good moderator to provide back pressure and you are using all that extra air volume in the shroud to quiet the shot. I still would crown the Impacts as king of the airguns 
. I know there will be LOTS that disagree lol.

Not sure why maybe because your ear is not right by the barrel, But the GKl and the Rex , also PP700 and even the PP750 are so muffled by a LDC you start checking for stuck pellets in the barrel,,, I put a , I just grabbed it as it was close , A donny FL Sumo on my new Reximex pistol The first shot I thought dam pellet stuck in barrel,, Flipped me out it was so quite Like a I spy move gun POOF,,,,

Seems some of these noise reduction devices are headed in the wrong direction! My old Tanto and FX DonnyFL seem much quieter than these new ones. Also, the older Huma-Air MOD30's and MOD 40's seem much quieter than the newer versions. Not sure what's causing this trend...
I will say my stock M4 Mod is quieter than most of the dedicated Moderators I have. I use it on my .22 and .25 barrels and an old style DonnyFL FX on the .30 Cal barrel. I use an older version Huma-Air MOD40 on the DRS, seems anything else is too loud! I did order a new 1.5" Buckrail modular for the DRS, but I'd be surprised if it was quieter than the MOD40!

I just want to know who in the world has heard a mouse fart? Why do we use this phrase? Isn't it easier to describe the sound level you desire for a particular environment?

the Government will pay you to do a study of any information they do not have . Seriously ! If you can send in a essay giving the nature of the study and the suspected results they will pay for the study and the equipment to accomplish the task .
A guy did this with Cow Flatulence over the states of Wisc. and TX . ( BTW Wisc had more atmospheric gas than TX but it was unproven whether it was strictly Cow Flatulency )

You're just hard of hearing if you describe any pneumatic rifle as mouse fart quiet. Go ask your child, niece, or nephew if they deem it so...

@snakem To your point, I think that's a good thing that the FX got the sound suppression right in the design phase. I wish more air rifles were designed that way. Many have OEM moderators and shrouds that do not render the airgun suburban-backyard friendly when tuned to a moderate power level.

This is a 100% subjective topic. I agree with you OP. I had an m3 .25 with a 600mm barrel and used nothing more than the stock metal hollow fx moderator. The only description I can give to it is that for me I have no idea why you would need quieter. I was the same way. I couldn’t believe the 33.95 pellets were actually going 900 fps.
