Headaches, Yikes!
Don't forget a lot of the catless exhaust is unconverted carbon monoxide which tightly binds hemoglobin. Carbon monoxide is actually odorless, but far more toxic than the gassy smell. Surely if you can smell the fumes, you're also getting too much carbon monoxide... the first symptom of which is a headache.

Maybe those running catless want to consider placing one of those home carbon monoxide monitors in their car, LOL!
