After replacing EGR valve, solenoid, spark plugs, IAT sensor I have noticed that I am not getting any pressure from the exhaust system at the tailpipe. Should I look more at the catalytic converter, or focus on other parts?
Do you
have the same problem?

It runs kind of rough and hot. I am not getting good gas mileage either. Is it possible that the cat converter is bad or clogged, or maybe the muffler because it is kind of loud as well.

Yes that is likely need to have exhaust back pressure tested. If can't afford locate and remove os sensor in exhaust in front of CAT. Performance improves then CAT blocked
