I've created this simple_filter:

This is email, being sent via sendmail command, after it has been filtered:

I think it should not be.
Should not be what? It's unclear what you refer to here.
Filter is using this command:
/usr/local/sbin/sendmail -G -i -f r...@example1.com j...@example2.com
<msg-headers+body-from-above>
The sendmail commend is a pipe. Don't put headers+body on the
command line.
I have 2 problems
Above command, if used as a root user results in MODIFIED headers+body
msg-headers+body MUST be exactly same, after it pass through filter
and STAY that way, until it leaves my server.
As first 2 lines below shows, another Received: header, has been
added, as soon as it passes through sendmail

Yes, postfix adds a Received: header when a mail is received.
There is no option to turn this off.
You may be able to later remove the header with an appropriate
header_checks entry, but be careful when removing headers.
Second problem:
If msg-headers+body from begening of this post, is being sent as:
/usr/local/sbin/sendmail -G -i -f r...@example1.com j...@example2.com
<msg-headers+body>
The sendmail command is a pipe.
If you describe what original problem you're trying to solve
maybe you can get some better pointers.
