So I’m installing a cat delete and realize my right side is missing a 02 sensor hole. Why would this be? And what should i do? Left side has a 02 sensor hole. Seems like they did it on purpose because the pics i see one doesn’t have the o2 sensor hole. Looks like another company did the same thing. One missing a 02 sensor hole. Waiting until the store opens so i can try calling them and asking why its missing a hole.

I am guessing because cat deletes are normally only legal for off road track use. If you are bypassing an EPA approved exhaust system then the manufacturer was bound by those laws. I ran into similar on my C3. A road exhaust was required to have cats, but off road could bypass. The manufacturer could not sell me just bypasses or risk a $15k fine per instance. I had a local exhaust installer tell me the same.
if you do it yourself maybe. No legit exhaust shop will touch it. Altering exhausts carries pretty steep fines these days. With the C3 I could buy the entire exhaust without cats for off road only but to buy just bypasses, illegal. In my case, when I bought the first street exhaust with high flows, there was still EPA testing where I lived. 1 year later the Fed lifted testing on 78s so I wanted to eliminate cats. Even with that the exhaust fabricator wouldn't touch it. With newer Vettes, better move fast. The EPA is working to emulate CA law where an aftermarket exhaust cannot exceed stock noise levels of 75db or emit no more emissions than stock. With NPP I personally think the C8 exhaust sounds great.
