Assuming you mean the New Edge Cougar, 1999-2002, then yes. Thorough testing on newcougar.org found that the best choice for exhaust is a 2.5 inch, mandrel bent, stainless system with the pre-cats removed, or replaced by completely new headers, such as those made by msds or weapon r.
The answer depends upon the displacement of the engine, type of piping used, composition of the muffler, exhaust type, and whether the vehicle is naturally aspirated or uses forced induction.
Does increasing the diameter of your exhaust pipe leading from the engine increase exhaust flow and therefore lessen engine burden causing an increase in horsepower? The answer for that is yes, but is negligible. Maybe 3-15 horsepower at best.

Upgrade the intake, exhaust, and fuel injectors.
The 1991-1997 Lincoln Town Car with the standard 4.6L engine has 210 horsepower if it has dual exhaust. Otherwise, the power is about 190 horsepower with the single exhaust.
rumored to be 325hp and can get more by timing and exhaust. rumored to be 325hp and can get more by timing and exhaust.
"cc" means cubic centimeter which is a unit of volume. There is no correlation between volume (displacement) and horsepower of an engine. With a particular engine you could get a certain amount of horsepower, however adding a turbo/supercharger does not change the displacement of an engine, but it adds horsepower.
The advantages of having dual exhaust, if it is a true dual exhaust, include increased gas mileage, cooler engine temperature, and more engine horsepower. However, if it is not a true dual exhaust, it doesn't matter how many exhaust ports there are, there will be no advantage.
depends on a few factors. compression, carb jet, airflow and exhaust, you can reach 7 horsepower in the right conditions.
For a 1992 Ford Crown Victoria , 4.6 liter V8 engine : Base and LX ( that has single exhaust ) ( 190 horsepower ) Touring ( that has dual exhaust ) ( 210 horsepower )
Electronic ignition is a great relatively easy adjustment, also you can add a dual exhaust, upgrade your camshaft ( requires pulling the engine), and I'm not sure but possibly adding a 4 barrel carbeurator.
depends on rpm, intake and exhaust, manufacturer,type of fuel etc..
