You always have an option!
Sell it on the Yellow, and contact someone who makes what you need. Tony at Talon Tunes can quiet that beast, as can Neil Clague, among others.

Thr frame extender I have has the end cap sealed and the barrel bushing is removed. The same set screw that holds the barrel bushing holds the frame extender. Not aure I have any options.
They just drop in.
You unscrew the end cap and the cup type baffles will drop in and hit the front barrel bushing, each additional bushing fits on top of the other. You add as many as will fit and screw the end cap back on the shroud. It doesn’t have to be a perfect fit between the last baffle and the end cap, just close.
Makes a big difference.
Some have used washers 1/4″ hole X 3/4″ diameter (or whatever is the inside diameter of the shroud) and these washers are “spaced” apart by either a length of spring, a piece of pvc, copper, or brass tubing about 1″ long. Again, you fit as many washers as will go in, up to the end cap. This disrupts the air flow, air harmonics, and slows the discharge a lot. All of this, with the rear shroud vents, will reduce the muzzle pressure a lot and thus bring the sound levels down substantially.
Let me know if you have questions.

How would they be mounted in there?
A frame extender merely allows more space for the compacted air to expand, thus reducing its sound signature.
To slow the air expansion, you need baffles for the air to force its way through before existing the muzzle of the shroud.
Another means to reduce the explosive air pressure is to vent it through the bottom back of the shroud, in front of the rear baffle, and to the bottom of the frame into the forearm. Six holes, 1/8″ diameter, dampened with apiece of felt, inside or out of the shroud, if there is venting sound you can hear.
The baffles can be made from washers and springs to seperate them, or even a piece of pvc pipe can be cut to lengths to seperate the washer baffles. The better idea is to give Jim Gaska a PM (Marmot_Militia) and ask if he can mill some cup baffles to fit inside the shroud. He makes them for $5 a pop for the Marauder. You need five or six at least.
There’s a lot of information regarding this subject in the “Shrouds” section. Do a “search” on Condor, baffles, etc, and you should find a lot of info.

Not a bad idea! Its a bunch less noise than without it, but not silent.
