Hi all. First off, please forgive me for asking questions I'm sure have already been answered, but I'm new here and reading through 180+ pages is a daunting task. So I have an N/A legacy, so would this still work? Would it impact the performance at all? lastly, would it pass inspection, or would I have to take it of then put it back on whenever I got it inspected? Again, sorry for the amateur questions.
