Replaced exhaust manifold gaskets but I still have a severe exhaust leak on the passenger side. Manifold did not show any signs of cracks. What could be causing the leak?

Check the air tube at the back of the engine
connecting the two heads together

Hi, I just installed an after market exhaust on my bronco 351 and I'm having a leak from the same side, I looked by my transmission on the passenger side and there's a metal tube that's sitting on the lip of the tranny pan that leads to the back of the engine. Is this supposed to be connected to the engine? Also he did not put an o2 sensor on it, is that going to affect my engine?

What year is the bronco
it is the EGR tube
if it had an o2 sensor you should put it back
but some of the after market manifold comes with little extra holes and plugs to make them fit more years and model car and truck universal
