Novitec sounds great. Big big difference [ame=http://www.youtube.com/watch?v=aBzDy42lsm0]Novitec Rosso Ferrari FF Exhaust-System - YouTube[/ame]
I've just had the Capristo system installed on my FF. Full exhaust system, with X-pipe and remote control unit. Sounds amazing! I was a little apprehensive as the FF sounds so good out of the box, I didn't' want to ruin it, but the Capristo system just accentuates what's there. I keep it on its standard setting, setting 1 rather than 2 as I find that on setting 2, with the valves open all the time, at low speed it produces a very deep sound that in traffic resonates and drones too much. On the standard setting, the valves open after 4K revs or so, as per Ferrari's own system, which for me gives the perfect balance. Very pleased with it. Also far more reasonable cost wise than the full Novitec system.
The sports exhaust option only refers to the design of the tips and are only cosmetic. The sound doesn't change. I have the same as you. The Capristo system utilises the existing Ferrari tips. Here in the UK the cost for the Capristo is circa £4.5K plus fitting. The Novitec system is double that. I'm very pleased with mine! Thoroughly recommend it!
Hey Mark, I tried to PM you but your box is full. Let me know if I can help you out with the exhaust.
