Advice please

Mt Tam I am

I would like to ask for some advice.
The set up: Nissan has offered me a 7 year/100,000 mile warranty extension as compensation for my oil consumption issue, resulting in a new short block replacement. Warranty extends only to power train and exhaust. I already have Nissan Gold warranty 8 year/84,000 almost bumper to bumper already. It has a $50 deductible. I have planned to modify the exhaust. Since in 8 years, I will never drive anywhere near the 84,000 miles, 100,000 only sounds better. I do intend to drive this car well beyond 8 years.
Question: Am I gaining anything? Should I continue to ask for new Catalytic converters, since they have already had six quarts of oil burned over them? Should I ask for something else.
Thank you in advance.
