Even though it's catted it'll throw a ses light? Then I wouldn't be able to pass inspection right? I have a jb4 with auto clear but I have inspection in a few months.. Just debating whether I want to go Catless or not..

That's correct. Since it's high flow cat, it does not meet emission requirement and BMW software will detect it as if there is problem with cat.

Benefit of high flow cat is that you still gain great power from factory downpipe and you don't have to deal with stinky smell produced from catless downpipe.
