The flex section is broken on the Sonata. It doesn't look like I have the room to weld in a new fleet section, at least not while on the vehicle. The new one comes with bolts/nuts to install, does anyone know if the manifold side is studs or bolts? They are rusted badly and don't even have threads anymore. I can see the studs ever coming out and may require a new converter/manifold.

Anyone replace this piece? Any tips?

 

If they are bolts you should be able to see the heads of the bolts.
