Add me to the list! Full 6-1 system, cats, double H, Fabio's mufflers!! Got my car back from the shop yesterday (still working on the valve controller but honestly not sure it needs it). I've already put a full tank of gas through the car it's that addictive! I have so many things to say, most which have been said before. One unexpected standout is that my car now has ZERO drone or booming noise at idle and cruising speeds which was a huge drawback of the factory HGTC mufflers in my opinion. Fabio's system has surprisingly made my car significantly more "mellow" at low speeds and constant highway RPM and I couldn't be happier with that transformation which should encourage even more driving! I'm really happy with the almost night and day difference between windows up and windows down / outside. At full throttle windows up the car sounds phenomenal but not obnoxious or tiresome in anyway. I was a little worried that the car might lose its Maranello GT character but that couldn't be further from the truth. It literally just sounds how a 500hp V12 Ferrari should from the drivers seat with no embellishment. However, when you roll down the windows or drive next to some hard surfaces... holy cow it's insane! Performance gain is definitely noticeable from seat of pants and confirmed with consistently over 1 second improvement to my stock 100-200kph times on Dragy so I think that probably lines up with the ~50hp gain others have mentioned. These Pirellis have no chance in 2nd so will have some fun lighting them up and will get some proper PS4S on there soon. Also I'm really curious what a proper tune will do in the future when the gated conversion is done. I tend to find the trope "it transforms the car" a little overused when discussing aftermarket parts but dang this is pretty close.
