Quick search yielded these possibilities.
I notice catalytic converter is on the list. When they age, the interior breaks down and can plug the exhaust.

I had this happen on one of the uppers.
soliution for me was to remove all 4 of the converters. Here are a few causes that trigger the P0410 trouble code.

• Worn one-way check valve
• Blocked air injection system air intake
• Defective O2 sensor isn’t responding to changes quick enough
• Catalytic converter partially blocked because of exhaust backpressure increases
• Bad contact of air injection pump relay
• Blown air injection fuse
