Alfadog Posted July 20, 2002 Share #1 Posted July 20, 2002 Just wondering - were they standard on '71 Z's as I think I have one (either that or 2 mufflers...) but I found that they were only standard on all cars from the mid-70s... Link to comment Share on other sites More sharing options...
72zcar Posted July 20, 2002 Share #2 Posted July 20, 2002 no cat on a 71...thats a pre muffler I think its called. If I'm wrong someone can correct me... Link to comment Share on other sites More sharing options...
2ManyZs Posted July 20, 2002 Share #3 Posted July 20, 2002 It's a pre-muffler or resonator, whichever you want to call it. I think the first of the Z's that had a catalytic converter was the 79 ZX. Link to comment Share on other sites More sharing options...
Zvoiture Posted July 20, 2002 Share #4 Posted July 20, 2002 Ummm...'79 for "49 state legal" maybe....here in the Peoples Republic of California I believe they started in '75 with the FI vehicles. If not, then definitely by '76.steve(test pipe)77 Link to comment Share on other sites More sharing options...
MRTOOTH Posted July 26, 2002 Share #5 Posted July 26, 2002 The 280Z's shipped to Calafornia have them, my 75' does. Link to comment Share on other sites More sharing options...
