In modifying anything related to emissions you are treading on thin ice! Not only must you pass whatever local inspections you may be responsible for you must also consider someday you may sell your car and it may go to another state. Just imagine what happens when the car won't be able to be registered by the new owner because of something you did. Now he may have legal recourse to force the sale to be reversed or maybe sue you for whatever it may cost to undo what you have done. My advice is to do any mods so that they are reversible and if you do sell the car with them in place to make sure that you have informed the prospective buyer so that he is fully aware of all of the implications. In some states not only do you have to pass a tailpipe test but they also conduct a visual inspection to verify no tampering. You never know where the car will wind up. In some states not only do you have to go for inspections but they also have "rolling inspections". They can pull you over for a random inspection. This happens all the time for trucks and is not common for cars but in the future things may get tougher and if you modified your car you may be taking a risk. The small gains you may achieve are not worth the risk IMHO. Many times a correctly operating car properly set up will run better than a poorly maintained car with an inoperative emmision system. It will warm up faster, use less gas, and in the long run be cheaper. If you have trouble with the car and the emission systems are disabled the first thing a mechanic would do is not try to fix the car but to try to get the emission systems going again to rule out their causing the problems. The Delorean has a very good engine system with emisions better than most current model cars. Anything modifacations you do will just make it worse, not better. The car was certified by the EPA with ALL of the systems in place and in working order.
