Aventador exhaust

[e11]

Hi guys,

Silly question, but how do I know if my car has the sports exhaust upgrade, or not? The dealer I bought it from couldn't tell me at the time and it wasn't really a big deal for me.

Now, having had the car a month or so, it just feels too quiet. In Strada mode it's deathly silent - although good for the neighbours! In sport it opens up, but even then doesn't seem as loud as my Gallardo was! Being a V12, surely it should be louder?

Also - any reason why the enhance sport sound doesn't kick in until driving it for at least 5 minutes? Doesn't make sense why the sound change isn't instant after initial start-up!

Thanks in advance!
