To each their own, I have the Capristo on the F type and that is brutal. The above comment about the "hardcore and brutish V6" is obviously nonsense, you cannot have it both ways. the V8 is the brute, too much for some and again that is fine, it will be interesting to hear the inline 6 when it comes out.
You cannot have a high revving Ferrari sound in a high torque, low rpm, slow revving V8 engine .... bought the wrong car ...

As others have mentioned, the over run is programmed so an after market exhaust is mainly going to change the volume and maybe a little more base over the stock exhaust.
