HELP!! with my 75 Dart

I Will climb under her and take a closer look.. You've got my curiosity up.. You'd think the shop that claimed they knew what they were doing..would have explored that possibility.. Thx
FYI,that one was kinked above the rear end in the bend above the axle. It had pulled away from the exhaust tip, but the tip hadn't moved so I didn't notice it. Run your hand up and around, was hard to see from just crawling underneath and eyeballing it.
