It's definitely safe, I mean there are flex fuel cars running around from the factory that definitely have factory catalytic converters due to emissions laws.
I ran it most of last season with no issues, although I swapped in my "Higher Flow" unit for some racing events. ahem.
Leaded Race Gas will coat the inside of the cat and can ruin it in short order, definitely avoid that situation.
