I hope this is of help. I know that the videos are available but I found them a little hard to see the detail So you can use this in conjunction with the videos if you wish. CLICK ON THE PICTURES TO ENLARGE.
It's important to get it right, the servo motor must be left connected electrically. If it's not you will have an engine warning light illuminated on the dash. When this is lit the bike is in 'get you home mode'. It will be significantly down on power and use loads of fuel.
I have met one CBF1000F owner who was riding around like this. He though his bike was down on power and had noticed the increased fuel usage. The bike will be running very rich and long term use could cause early bore wear.
It's not a difficult operation, any one should be able to do it with very few tools needed.
This picture shows the standard Honda exhaust system. The cover at the front over the exhaust valve is not a pretty thing.

This picture looking underneath the engine just in front of the rear wheel shows the servo motor that operates two push pull cable which open and close the exhaust valve on the silencer.
The bolt in the centre of the picture mounts the motor to the bike. Use an 8mm socket on a short extension and remove this bolt. Right at the bottom of the picture you can see the greeny colored clip which holds the cable connector to the mounting plate, squeeze the outer legs in and push the clip upwards. The motor then needs tilting down and pushing up to slide it off a peg

This picture shows the exhaust valve, the other end of the push pull cables. I think its best not to disconnect the cables at this end. They will be moving and you will have to do a bodge and tie them up, always the possibility of water ingress too.
Picture taken from the left side of the bike.

This is what the servo motor assembly looks like when removed. You can clearly see the two cables and the electrical harness.

Carefully peel back the water proof cover so you can get at the push pull cable ends. You will need to remove the round white nylon cable actuator. You can see from the picture that the motor shaft has a flat side to it. On the same side as this flat, on the edge is a small hole, use a 2.5mm Allen key to remove a cheese headed screw, you need to remove it and not just slacken it off.
Gently pry the nylon disc upwards and off the shaft. Make a note which way up the disc fits. Unhook the cable ends, slide the cable wire out of their guides in the motor housing. The cables can then be gently teased out of the rubber cover. Refit the nylon disc, refit the screw and replace the cover. You may want to mark one cable and its position before you remove them, just so it's easy to retrofit should you need to. I just used a bit of red touch up paint.

Now I would strongly recommend that you plug the holes left in the cover after the cables have been taken out. It will keep water from getting in, the unit is just in front of the back wheel and you really don't want the servo motor to pack up. I used two short pieces of plastic tube blocked off with a suitable self tapper.
Replace the servo motor, firstly locate the servo motor on the peg, then swing it round to line up the mount for the bolt. Don't forget to clip the harness plug mount in the bottom plate.

Next slacken off the bolt under the rear footrest, using a 6mm Allen key and a 12mm spanner on the nut at the back.

Now using a 12mm socket on a short extension slacken off the exhaust clamp.

Now remove the nut from the back of the silencer mounting bolt, (under the rear footrest). Holding the silencer with one hand pull the bolt out and be careful to note where the two washers are fitted so you can replace them in the correct position. Slide the silence off the exhaust pipe.
You can see the cables to the exhaust valve, still attached. Don't forget to put this all away in a nice safe place.

You don't need me to tell you how to fit your nice new silencer? I hope not.
This is my nice new titanium Remus can, which I'm absolutely delighted with. It's not noisy enough to annoy but gives the bike a throaty growl.
