u can't modify your car with parts that are not homologated(special testing procedure by officials if modification is safe to use). So if u want to use an exhoust can and it has a homologation sign (like TUV or EU approved) u can put it on but if u made something yourself,to have it legally you would have to go through the procedure to approve it for automotive vehicles. That is the theory,but for example in blegium noone is asking u to take technical check on your motorbike,so its up to you wheather you will go for a check. In that case only if u run something extreem (like open exhaust or i don't know...horns on your steering ) and police can spot you,you may have some trouble.In my case i modified a Yamaha FZR , i added a turbocharger but found no problems what so ever.I can imagine if a guy who bought it from me had some crash,insurance company could say they won't pay because Yama was modified and not approved so it could have been a source of an accident.
Take it for a car then situatiion look different.car has to be checked by a technician every year.Technician can spot some equipement you added and say no to prolong your papers.In practice i have never heard of any problems,but if u had no exhaust or u cut out the catalisator...the story could be different.

I can imagine if some guys (other topic on this forum) want to put an impeller on the roof of their car it can draw unwanted attention.I would just put some sticker on the HHO unit and disguise it as a filter noone will ask any questions.Once i had a kind of a cooler and i was driving with a connected CO2 tank in my trunk to run the cooling.I went for a tch check and noone asked nothing.

Its up to u ,personnaly i would just made a good story and stick to it

I suppose I could disguise it as a windscreen-washer bottle. Most of the police in this country don't know the difference between an exhaust pipe and a drain pipe, so I need not worry about them. I suppose that I would just have to make it easy to remove, and remove it each year when the MOT is due.

It is easier to ask for forgiveness than it is for permission.

I  was  wondering  about   putting   the  electrolizer  in the  interior of the car

all  that  would need to go through the firewall are a couple wires and a tube  ........easy  to disconnect  for inspections .


Also .....I am wondering  how to make it  work  through the winter .
If it inside  the passenger  compartemt  it is in effect  in a  solar  collector .
It  would be  quite a bit  easier  to keep it  from freezing  in the passenger  compartment  than it would in the engine  bay

One  thing I am not sure about  would be   condensation in the  tube going into the engine  bay
