Should I do a Cat delete on '75 Duster

The original poster is in California and his car is old enough now that it has aged out of the states smog testing requirements. At this point I believe he can legally perform any engine mods he wants. That’s one of the reasons I held on to my Duster for all these years. I was looking forward to the day it would age out. As fate would have it shortly after it did I moved out of state and brought the car with me to PA.
