F430 sound changed

Dear Chatmates

I have just picked up the car from my dealer, I had the pipes changed because of a Ferrari campaign, and first revision done, cost aprox 1800€, also installed Macarbon carbon airboxes, look great.
I drived it for 2 hours and I realise the engine sound has chaged, sound more like air and not so metalic and precise as before (but temperatures and bar are all ok), dealer say because pipes are new, also feel the car more vibrating (maybe because also installed racing seats).
I stoped and start again and engine does not change sound as before, dealer say it is because of the temperature, we are at 35 degreesC.
Is the dealer right? is that normal?
Thanks for your comments.

Regards

 

I didn't know a F430 campaign existed to change exhaust pipes, only exhaust brackets.

 

Campaign exists for Chasis 1450--. Year 2006

 

I had the campaign done and they changed the brackets and the pipes. I didn't notice any difference in the sound.

 

Total BS. I had it done too (on the old car-2005). No difference!!

 

I have seen a previous post on this where Wil, at Maranello Racing, had taken pictures of the supposedly new tail pipes. This is the link:

I have some friends with F430 and the new pipes and no sound difference..

 

The brackets can't be changed on their own. I have had them replaced on one side already. The other side just went bad this week. I asked them if they can just get brackets without changing tips etc. They said Ferrari is working on a fix but that at this time the whole thing has to be swapped.

 

I had the entire set up brackets and tips replaced on Friday before taking delivery of my car and have been driving all weekend and the rattle has returned! Not sure what to do? Its not quite as bad as it was before it was replaced but I suspect it will get there. Im loving the car so much at the moment that Im not even considering sending it to the dealer yet.

 

I have parked the car in the garage since friday, I will use it tomorrow and make another test.
Do new carbon airbox may influence?
