Car was originally 6 cyl with a cat. Hasnt been a cat on it since converted to v8 in 85 or 86 .I can probably get it certed without cats . Anyone know any of the rulings on something this old . Or just go with punched out ones and be safe??. I want to up grade to 3 inch pipes but not this year. So , I didnt really want to have to deal with cats For this yr only. Ins co,s want a safety and appraisal , before re in suring it . Bastards..77.
