I don't mind the factory race exhaust I have fitted. I think it sounds better than the Quicksilver in that video. It is fairly easy to drive around the drone point as well as it occurs over a fairly narrow speed range. If I was driving the car everyday it may be different but for occasional use I like the rawness it gives. I will likely give Alfa Works a call at some point just to try their 4C demo to see what difference their suspension mounting blocks make to the steering.
