Any problems putting 3’ exhaust on 70 Dart ?

I consider my Dart to be a work of art in progress. Not just a bunch of bolt on parts.
I’ll post pics when I’m done and it think you will also consider it a work of art. I do value opinions otherwise I wouldn’t have been able to accomplish what I have. I have taken many ideas and made up some of my own. It’s like when I was growing up my mom was the boss but when my dad was the ultimate authority if he said we are doing this way it was end of discussion!!
