I can try to take a pic of my setup when I get off work I remember I used the clamps it came with only one that came off is the connection you see right by the flex joint in your pic that thing popped clean off after a few redlines haha ended up just having a shop weld it everything else I used came with the headers except gaskets at the heads don't remember cutting anything only remember the pain to fit that piece in and that I had to bang out the firewall to fit an o2 you should be able to just put that clamp on with that room let me confirm though
