SupraIV loud exhaust defective flap

I'm having trouble with my 2022 Toyota SupraIV with a gasoline engine. At around 24859 km, the exhaust is louder than usual, especially after a cold start, and there's an error stored. Seems like the exhaust flaps aren't working right. Any advice?

Hey! Loud exhaust and error codes definitely point to a problem. Since you mentioned exhaust flaps, could be the flap actuator. Is the noise constant, or does it change after the engine warms up? Have you checked for exhaust blockage?

Thanks! The noise is worst during a cold start and gets a bit better as the engine warms up, but it's still louder than normal. I haven't checked for a blockage; where would I find that?

Alright, the cold start noise makes the flap issue pretty likely. I wouldn't recommend poking around the exhaust without proper tools. It's probably best to get it checked at a workshop. Sounds like a defective exhaust flap and probably a quick fix for them.

Thanks for the advice. I took the SupraIV to a workshop, and they confirmed the exhaust flap was defective. The repair cost was 190€. The issue is resolved now!
