    Has anyone here installed an exhaust valve controller on an 812 (e.g. Capristo unit or similar)?
    If so, how was the installation in terms of cost and complexity?
    And, when the valves are set to "open all the time" is there any drone noise?
    Any other comments in favor or against would be appreciated.
    Thank you!

    Yup, had my dealer do it. I think they charged me around $1k?

    Anyway it's not really droney but if it annoys you can can always flip the switch. I play with mine all the time as it's mounted under the steering column super discreetly.

    Capristo? You happen to have a picture? I have one installed on my F12 and plan to do the same on my 812 when it arrives in the next couple months. Currently, it just sits loosely on the center armrest console. Semi-permanent mount under wheel sounds like a much better solution.

    Thank you for your reply. Do you find that the valves open setting makes low rpm driving sound better than the factory original (i.e. closed) setting?

    With the F12, I think open valves at low rpm definitely improved the sound in the cabin. But I have not driven the 812. Perhaps the 812 sounds better than the F12 at low rpm, even with the valves colsed?

    Or, perhaps the 812 really “needs” an exhaust controller to open the valves at low rpm just as much as the F12 did.

    I’d appreciate your thoughts on these questions.

    I had a Capristo one fitted, it does not make as much difference as the F12 one did, but it does make it louder so worth doing, comes with new dongle to so you can leave them open by default

    I don't think mine is Capistro but I'm not sure exactly what the dealer used. Mine is just a toggle switch mounted under the steering column.

    It seems to not make as much of a difference as the F12 but that's subjective. I only have 500 miles on the car so I'm not sure my opinion is that strong either way.

    I had the Capristo valve controller on the F12 but simplified my life by having the dealer just pin the valves open on the FF, 488, and 812.

    I had this done and don't think it was really worth it from inside the car. The difference outside the car is much greater. I wanted to hear more from it like the 458 did. Any other suggestions to get more sound into the cabin? Obviously exhaust and cat-delete, but in LA, they are cracking down on loud exhausts...

    I roll my windows down if I want more cabin sound but I don't care if it's louder at idle or not. I like the sound on acceleration and the fact that it seems to have two distinctly different sounds. It wails up to about 7k and above thta it gets really deep and louder because I guess the intake is sucking more air at higher rpm but it sounds like it's sucking down a lot more gas. Anyway that's how it sounds to me.

    I suppose I should wait until the break-in is done. I know it’s not specific, but trying not to push it too hard until we’ve driven 500mi or so. I have experienced that two stage acceleration though. It’s intoxicating. I do notice quite a lot of wind noise with windows down. Considerable amount more than the 458. I also appreciate how mechanical it sounds, and the fact that there no exhaust rasp as you push a little deeper into the pedal.

    I just pinned my valves today. Went to O’Reiley’s and bought a package of assorted vacuum caps, jacked up the car, pulled off the rear tires, reached in and did it in 5 mins. One cap fits perfectly over the valve nipple and another over the vacuum hose & sealed it with some black electrical tape. Sounds perfect.

    Do you think it can be done on a lift without removing the rear tires?

    Yes. One can easily reach the vacuum hose.

    Tactile dexterity is a must. I'd also have a short piece of wire ready to retrieve the dropped cap (which u will drop at least one) when u try to put it on the nipple. The only potential problem would be pulling on the vacuum hose and it detaching from the main line and not the valve, which would require at least pulling the tire if not the under body.

    Take a look and wiggle your hand back in there. The vacuum hose is bright blue and again, easily reached.

    The only issue with pulling the tire is that Ferrari use wheel bolts and not the easier lug/nut combination, which is a PITA to do. But if you track your car any it's an opportune time to clean off the rubber.

    FYI wheel bolt tension is 120 Nm. IIRC 88.5 Ft-lbs

    I installed the same Capristo unit on my 812 that I previously had on my F12. Candidly, I set it to open, and never have once closed it. Sounds great. If anything, I wish it were just a touch louder. It’s a good, cheap, mod for a more impactful exhaust note.

    Yes. Louder in the cabin would be nice. Plenty loud outside, but I can’t tell it’s on very easily unless I’m idling.

    Is there a DYI protocol or video to pin these valves open on the F12?

    All you have to do is look into the rear wheel well. Blue hose and exhaust valve. This video is on an F12 but you get the gist. Skip to 10:40 and you will see the hose.

    I had the capristo installed on my 812SF and I notice it when it idles, I think on the run down in the rpm while under load it does seem to have more exhaust sound if you know what I mean.
