I had some exhaust leaks where my headers went to y pipe. I had them welded which fixed the issue but i did find a small spot or two that i had to reweld myself.

Is there any good way to find if there are any exhaust leaks?

My o2 sensors read pretty close to the same thing but they are not exact. Although i dont expect them to be exact anyways.

Black soot marks will occur so that's one way to find a leak.

If the cars in the air on a hoist & running you will hear any leaks or feel the escaping gasses.

You could Sea-Foam your car and restrict the outlet(s) . . . You'll see any leaks !

a smoke machine might be helpful.

condensation dripping out is also a good indicator

Smoke works best...... vapor from dry ice would work in a pinch too. Disconnect the fan before doing it. But run vehicle while blowing smoke or dry ice vapor around suspected area. Watch for areas where smoke puffs or changes direction. Remember to hook fan back up after u find leak.
