Why does nobody use high flow cats?

I have gone the DP route before on a 350z and the noise was horrible (not trying to hate) as well as the fact you can't pass inspection. Went to high flow cats and was so happy the raspy sound went away, and was able to pass inspection.

I have seen AR makes a high flow cat but it's like $1k which is a bit ridiculous considering i paid half that for the 350z and that required two pipes.

Am i missing something or is the rasp not there and switching them before inspection once a year not that much work?
