I always kept the stock airbox handy for my Nissan since I had to smog it every two years and the WAI on it is not CARB compliant.
Only PIA for me was needing to start up and move my Pierce to get to the garage attic ladder.

Great that you found a shop that would gut that thing and not cry about CARB rules and whatnot.
