Evolve E-tronic exhaust maintenance

I was just shown an installation manual for the electronic valves on the Evolve exhaust and in it, it mentions that monthly maintenance for the valves includes lubricating the valve to prevent carbon build up on the valve. Is this consistent with what everyone else is experiencing?

It's a good idea to do this.

On our supercharged E92 M3 and E60 M5 we use the same valves.

We have not cleaned them or intend on doing so. The move freely and carry on working after thousands of miles. We have had zero failures of these valves so far.

However, cleaning them will definitely avoid any problems with carbon buildup and it is still recommended that a periodic service/clean is done.

What is the procedure for doing this? Do you need to remove the exhaust to clean it or is it just a matter of spraying something through the exhaust pipe?

What I did was take the valves out, spray some degreaser, let sit and then with a brush clean it up and wash and wipe with towel. Then taking some lubrication (I forget which brand it is, but my dad uses) and I just put it on the parts that move

Yes,

the exhaust valves are removable. Makes life much easier.

No need to remove the exhaust at all.

While you are down there you can also remove the tail pipes and give them a really good clean.
