96 LS400 : Catalytic Converter Removal
Members,
What are symptoms of a faulty catalytic converter ?
Furthermore,
Please inform me of any ramifications to which may arise If I remove my Catalytic Converter.
Gas mileage increase or decrease ?
Emissions Increase ?
Engine check light code will appear ?
Engine Power will increase ?
Feedback is welcomed.

your LS400 was designed by an elite world class engineering team, the likes of which even Mercedes and BMW were jealous of - your catalytic converters are some of the best ever designed. 
everyone I know who has removed them has regretted it, they have either lost power, lost fuel mileage, made the car into a smokin' stinker, made the car sound ghetto noisy, or some combination of all of those.
do a back pressure test at the pre-cat O2 sensor, if it is correct, then leave the cats alone, they are HELPING your engine, not hurting it! - get out of the 1975 hopped up Camaro way of thinking!

Members,

Furthermore,
Please inform me of any ramifications to which may arise If I remove my Catalytic Converter.
Gas mileage increase or decrease ? No real net gains from properly working cats being removed.
Emissions Increase ? Duh. HC increase many fold.
Engine check light code will appear ? again, duh. yes. multiple codes.
Engine Power will increase ? Minimal gains from removing properly working cats.
Feedback is welcomed.

How about you post the symptoms you are actually experiencing, rather than trying to find some correlation between your symptoms and what you hope/think/have been told is the problem.
There are some very knowledgable people on here who can help you, but you have to tell us what's wrong.
