Default Main Cat Delete O2 Sensor Help

Guys- Just received my main cat delete pipes from Norcal SS, they look great and ready to install.
I have read this FULL post and seeing many different ways to keep the CEL from coming on.
Looking for a PROVEN option to keep the CEL from coming on besides the obvious of tuning, whether itís the angle bid daddies or anti-foul.......
Please let me know what you used and how many miles without getting the CEL.
Thanks

I'm actually in the same boat. Just received my pipes last week and they are at my buddies shop getting ceramic coated now. I ordered the big daddies 90* fittings.
I did a ton of reading and I only recall 1 person saying they didn't work. I'm pretty sure the only PROVEN way it to tune the car...

My car is stored for the winter so I wont know if it throws a CEL or not until spring. If it does, I plan on removing the big daddies and welding the hole closed, then drilling a smaller hole.
I also do not want to tune yet.

Big daddy 90 degree cell fix installed last summer 2000 miles no cell yet. The driver side faces forward and passenger fits best facing rearward.

normal pipes on order. How many Big daddies do I need? Haven't been under there yet.
Should I get a fresh inspection sticker before installing? I would think it would not pass the sniffer without converters?

Thanks

2, one on each side. I was told by my mechanic who knows i have the cats deleted that the emission inspection in NY is read by a computer and not a sniffer, therefore he thinks that if the bid daddy's trick the o2 sensor then it will pass the emission test. I have not had an inspection yet so we will see.
