My old SL "JanMod" has one I made following a description in Garden Railways back in the 1980s.
Works a treat!
Now, that being said, over on the Dutch Yahoo 16mm group in the 200K odd messages and files section, there is a design of a Mamod exhaust regulator, basically a slide/dial design to increase/decrease backpressure to make the Mamod more controllable.
So yes, they can be designed to change performace, or not as in Chris' design, just to give a nice sound.
