I have not tried the moderator, but I have no doubt that it would deliver what you want - it looks large enough and Jim and Travis make great stuff. Judging by the threaded end, it looks to be over 8" long and about 1.5" in diameter, so just be sure that you are comfortable with that much extension on the (already quite long) Marauder. Mounted on a factory shroud, the gun would almost certainly be over 50" in overall length - but with a nearly silent shot!
I do have the shroud extension, and it does make for a slight reduction in sound level - it is noticable but not dramatic. While it was well made and functioned as inteneded, I ended up taking it off my gun as I was not comfortable with the added ~3" length on it. It just was awkward for me to be carrying something that long.
As a thought, the moderator on a shortened shroud might be a really good solution - you would still pick up a lot of volume of air space for noise reduction.
Of course you will be left with the reality that even with a stock .22 Marauder, the sound of the pellet hitting the target (or pest) is typically much louder than the firing of the gun.
