Yaris loud exhaust error

My 2010 Toyota Yaris with a gasoline engine is throwing an error and sounds like a tractor. The exhaust is way louder than usual, especially after a cold start. I'm guessing it's something with defective exhaust flaps. Anyone else experience this?

I had a similar issue with my Yaris. Error stored and louder exhaust noise. Is it possibly the flap actuator?

Where was the error stored, and was the louder noise constant, or only at certain times? I'm trying to figure out if it is a blockage or an exhaust component issue.

The error was in the engine control unit, related to the exhaust valves. The noise was more noticeable on startup and during acceleration. I'd recommend having a workshop take a look to pinpoint it exactly.

Thanks for the info! Took it to the workshop as you suggested. Turns out the exhaust flap was indeed defective. Repair cost was around 190€. Appreciate the help!
