cutting secondary cats

Can removing secondary cats void your warranty in anyway? like hpfp?

It shouldn't.
They need to prove the exhaust is at fault for whatever failure your car will have.

Supposedly any tampering with emissions VOIDS your warranty and heavy fines if they report you.

would the dealer check on a basic maintenance?
