So I had the infamous broken weld on the heat shield of the JK, took it into Jim’s Custom Exhaust to have him find and repair the weld for me. In the process, he noted that all 4 cats are shot (rattling and turning blue when hot), as well as my manifold having a crack it in. Doing some research, replacing the cat y-pipe is not cheap! Seeing prices around $1600!!! 
Then I came across this: epa.gov/oms/consumer/warr95fs.txt
It seems that major emissions parts are required to be covered by the manufacturer if failed within 8 years / 80,000 miles. WOW! This could be huge. Only bad part is this one clause:
"If your vehicle is within the age and mileage limits for the
applicable emissions warranty, the manufacturer can only deny coverage
if evidence shows that you have failed to properly maintain and use
your vehicle, causing the part or emission test failure. Some
examples of misuse and malmaintenance include the following:
* vehicle abuse such as off-road driving or overloading;"
Has anyone ever taken advantage of this federal law for their cats or other major emission components? Do you think I’m going to get denied due to off-roading or load with larger tires? I’m sure as hell not going to Paul Baileys, they refused to even sell me an extended warranty because I had a lift. I’m thinking of calling Claire Jeep, as JWO says they’re pretty chill with lifted jeeps and off-roading.
Just curious if anyone has any experience with this law and having warranty work done that is covered by it. Any comments are welcome, especially if from personal experience!
