I drilled out the cat on my 2014 FXDL, has a smaller outlet but still only took an hour to do the job.

There is a video on YouTube where a guy with CVO RG didnt cut anything. He bought a long *** drill bit and went in through the back after he removed the slip on. Then he vacuumed it out.
Looked very easy. Maybe easier than cutting it open and welding it back.
Edit: Found it.

2022 RKS - I would like to save some $$$ and decat my OEM header rather than buying new one, no need for me to spend $800 on fullsac.
Will overall final effect on performance of the bike be significantly different between using decatted OEM header vs expensive FullSac?
I run KhromeWerks mufflers
I would expect final effect on performance gains (when installing cams) would be negligible if any. Is my logic tinted?

These threads go off track quickly sometimes.
Yes it will void your warranty. Do not drill out the Cat, that's a waste of time. Cut it out properly or don't mess with it.
You said you have a 2022 (Road King Special)?
You currently use KhromeWerks mufflers.
You want to de-cat the headpipe.
Later on sometime you plan on a Cam swap.
Okay, go for it. With a De-cat headpipe your bike will run cooler and sound a bit better. You'll enjoy the ride while your saving money for the Cam swap. Wait a little longer, save a little more, and buy a new Cam and Headpipe. Or, swap the Cam and do the headpipe later. Don't forget, at this point you'll need a Tuner Module, because of the Cam swap.
It's no big deal either way for a simple Stage 2 setup.

Cut a window and knocked the whole brick out of my ‘13. About to do the same to my ‘15. The cat design is not worth a damn as a cat or anything else. Just better for everyone involved if it’s gone.

Warranty validity is going to be based on claim.
I replaced my stock head pipe for a Cobra Pro Chamber and Neighbor Haters. They were first, but I was still in original warranty. Had a few warranty items, front brake rotors, and i would need to think of the other minor isssues and or recalls.
Also had the extended service plan where the dealership did all my scheduled maintenance up to 3 years and 30k of which I hit 30k before 3 and never a question.
Even though I did the work meself along with snatching a $200 SEPro tuner new that I tuned the bike with, the service department never even mentioned my changes. Never said my warranty is or could or would be void.
I am of the mindset that the warranty that comes is good enough or I aint buying it. House, car, bike, household appliances, anything with a warranty, nothing extended.
The ESP was a paid up front service plan I chose for the new to me off the floor bike. Extra treat. Take in, get call, pick up. I now do my services like previously on all my other bikes Ive had.
But never heard a peep.
