So I've researched this up and down on the internet, cant find the issue. Here is the issue, my 92 es300 smells like exhaust in the cabin when at a stop(warming up in the morning, stop lights, etc.). The car also has to be set to outside air, if set to recirculate then there is no smell. I also know this issue is coming from the front end, b/c when I drive off(<20 mph) after having just started it, the car will smell like exhaust/gas on the drivers side if windows are rolled down. I've attempted to look at the exhaust under the car, but at the time there was a ton of noise so I couldnt hear anything.
Any known exhaust leaks on this car? Reasons why the car would be sucking a foul smell into the cabin at a stop?

You have an exhaust leak......very simple!!
Check the flex joint. It is very common to have an exhaust leak there.

Start the car and completely cover the exhaust outlet with the palm of your hand. The source of the leak will become evident by the sound.

It's easier with a helper.

Get this checked out ASAP because this exhaust leak may cost you more than a new exhaust system. (CO is a silent killer)
