Electric impact....
You can put a rag in the discharge/exhaust area as well, just don't cause a true blockage.

You mean cordless? Most are noticeably louder than my pneumatics.
OP, I seem to remember looking up a new QTIMAX body since the standards are more common on the used market. Came to the conclusion its not even close to worth it. Your best bet would be to buy a QTIMAX and sell your existing.
I find the actual hammering action of the socket to the bolt to be the loudest part, not the internal part of the gun. I try to wear ear protection because I don't know how else to make it quieter.
The hammering is certainly one of the loudest parts of an impacts operation but there is a very discernible drop in noise from the whine of the motor with the muffled versions. I can deafen a small shop with my MG725 simply running with no load. Pop the piece of foam in it and it becomes quite tolerable.

2135QTIMAX 86dBA (no load speed)
MG725 isn't quite as effiecient at quieting down but still goes from about 100 to 92ish dBA.
Keep in mind the human ear perceives a change of 10dBA to be about twice as loud.
