The exhaust system for leaks, or is it better to replace, as my car came from the East and wintery days.......lots of salt....uukkk

 

What I would do is bring your vehicle to meineke, and they will check for leaks on your entire exhaust system for free.

 

Do this at your own risk ...

Take a rag and with the RX in park at idle, try to plug the exhaust. You should not do that too long as eventually your engine will stall [and if it does you will have deposit on the spark plugs]. If there is a weak spot the exhuast will leak from there. For a sound system, the back pressure will build and the engine will lower in rpms.

If you don't hear any, see any, or smell any, keep driving and don't worry about it. It will let you know when it needs replaced.

 

Why do you think you have a leak, or are you just checking?

 

When my left rear window is open and I am by a retainig wall it seems loud.....

I dont know if that is normal and with my too lean CEL...was just wondering.

Also that pic that shows where to look for a crack just below catylitic converter seems okay but rust has made it not as clear..

 

There is an air pressure issue that causes that noise when just rear window is open. Exhaust leaks usually have a fluttering sound and the likely culrpit is this area here when that occurs.
