Thanks for the update . Great to see you are happy with the car on the long run . 

Strangely , my now old 997.2 , with 125'000 km got quieter .... but  I suspect a problem with my exhaust . 

That is strange, usually with problems with the exhaust it gets louder Smiley do you have sport exhaust? maybe the valves are opening fully?

I have the sports exhaust . Valves were stuck on open for the last 2 years , but now I suspect that at least one valve is stocked on closed
