Catalytic converter or converters are very loud

I’ve priced new setups because I haven’t
been able to distinguish exactly what is
causing the truck to be so loud when driving
it. I’ve heard about deleting the Cats
themselves and running straight pipes
instead.. When pricing all new pipes it was
nearly 1k uninstalled. I usually work on my
own vehicles and was wondering if anyone
had the same problem or possibly a solution
to this loud as V-6.. PS. I live in MS and I’m
not worried about emissions bs
