Thanks Comrade Charlie I thought it was 71 and older that didn't need to be smogged.
Blue72 thanks for the info. I should of done some research before asking. I've learned a lot about cats and mufflers in the few minutes on howstuffworks.com
Would anyone like to recommend where and what cats/mufflers to get? I see some stock v8 exhausts for sale on craigslist, and on ebay i'm finding decent priced magnaflow cats. I've never bought an exhaust system before. :/
