Exhaust Bolts/springs on 2000 Chevrolet Tracker

I am trying to tighten/loosen the exhaust pipe (flange between exhaust pipe and catalytic converter?) bolts/springs but am having a hard time figuring out what sized wrench I need for the exhaust bolts. Its difficult to see them and figure out what size wrench I need

Asked by for the 2000 Chevrolet Tracker
Most exhaust flange bolts on these are 14 mm.

From my experience, I'd try a 12mm or 14mm wrench and socket first. those are common sizes on Japanese cars for parts like this.
Thanks, I will try that
