From what I've read before on the reasoning for the high pitched wail coming from the McLaren I understood that it was because of their new exhaust for this year.
However, noone is still 100% sure that this is the case.

During the Friday practice sessions the sound was really evident especially with no other cars close. Just listening to the Mercs accelrate on to the main straight I could really hear the difference compared to every other car.

However, on the race day what happened after the safety car went off? The Mac's seemed to just die down. Maybe I'm imagining things and all the noise from all the other cars just made it less evident and much harder to pick but I'm sure that the McLaren's did not have that high pitched scream coming from them anymore.

Some people say its because the Merc has reached the "Magical" 20,000rpm mark. I however think most of it it because of there new exhaust design. I think that the ventulli tunnels under the car act as sort of a large exhuast tip, that may amplify the exhaust note.

I was sitting at the pit exit (Fangio stand) at this year's Australian GP, and the McLaren's certainly sounded different, a very high-pitched sound. I'd have to agree with the fact that the exhaust must be different.
Could it do with the fact that beryllium isn't used on engines anymore?
