Hello, i just bought some Rinehart 2 into 2 exhaust system for my 2016 street bob. I'm installing the rear pipe but I can't seem to be able to tighten the rear exhaust screw, the O2 sensor is way to close to the exhaust flange and I can't get a tool in to tighten the nut, does anyone have any ideas on what I can do? It's really frustrating 😧

 

Maybe remove the O2, install the pipes, then install the O2?
