I noticed a small round hole on the bottom side of the stock exhaust catalytic?   This is my second FJ and I don't recall seeing that before.  Of course I may not have looked on the bottom side of the exhaust on my last one.  Just wondering if this is normal on the FJ or is there something else going on?  The hole is on the bottom near the "corner" of the cat.  Looks perfectly round to me.  
 

I would say drainage for moisture and/or water.

Thanks that is what I was thinking but guess I never noticed one before.
