Mac y- pipe to stock convertor
I have a set of mac's on order for my 94 Z28 and upon looking under my car today I noticed that my cat is welded to the existing y pipe. Can I cut it off & use the old cat for the new y pipe? The mac Y pipe has a bolt on flange for the cat. How can I get it on to this pipe or do I need to get a new cat. I hopeing to install the headers myself without any welding.
