Peugeot 207 Loud Exhaust After Cold Start

Hey, I had similar symptoms with my old Opel Corsa – exhaust sounded like a tractor! Loud, especially on cold starts. Did you check the flap actuator? I remember reading somewhere that those things can seize up. Could be worth a look before you start tearing everything apart.

Could you elaborate on which specific components you inspected on your Opel Corsa when addressing the increased exhaust noise? Any details on the diagnostic procedure you followed would be greatly appreciated.

Honestly, I'm no mechanic. Just a DIYer. I poked around a bit, saw some rust, and decided it was beyond my skills. Took it to a workshop. They said it was the flap motor. Is it the same part you are talking about?

I appreciate you sharing your experience. The flap motor does indeed seem to be the culprit. As suspected, the exhaust flap was defective; the repair amounted to 190€ Thank you again for confirming my diagnosis.
