    I’m very very happy with the car, including the way it sounds. It will never sound like my 458 or an Aventador, but the car is exponentially better in every other way. Being able to keep the valves open is a little icing on the cake.

    And that in a nutshell is what the sound debate is all about. Sound is not as good but in every other measure the car is superior. Congrats Arnie!

    The only one thing that confuses me is when the valves were pinned you had a cel light but with the Capristo controller you don't. To me that doesn't make sense. I wonder what the dealer did to pin the values. This issue isn't observed with the 488 or Pista.

    I agree, which is why I asked for confirmation in writing. This was the response from Capristo when I ask for an explanation.

    “Our kit has a “piggyback” electronic pass through. The module is “in line” in the harness chain so the computer never gets a code that valves are not functioning. Whereas pinning them open you have the electronics getting no feedback and a change in vacuum pressure. Our module can then override factory function signal to keep valves open at all times as default and just use remote to go back to OEM control“

    Basically the controler tells the system everything is ok but you can open the valves the whole time and it still tells it all is ok, it lies to the sensor so you can do what you want

    Hey Buddy. It was around $1600 installed. And yes, I bought the package from my dealer.

    So you would think it wouldn’t effect the warranty, what did the dealer say about that?

    Never asked. It does make me feel comfortable that they did it though.

    If you can’t beat em , join em.
    What if instead of trying to defeat the GPF, one used a lighter and less sound reducing muffler?
    Could that improve the exhaust music?

    Even better would be a sound engineer working with one of the companies e.g Kline. But I guess they all take the easier route and just give an option with muffler delete.

    Doesn't help also with distributors like Vivid not actually having any videos and stating what the equipment is.

    Eurospares finally has parts diagrams for the F8 on their website:

    Just realized the GPF is integrated into the silencer (muffler). So it seems you could just replace the entire assembly (Like the Novitec valved exhaust) and leave the OEM CAT pipes in place. Might be a good starting point instead of replacing the upstream CAT pipes as well. Of course you’d have to add the “Techtronic” plug in to avoid CELs. Will be interesting to see more vendors solutions as they come to market.

    I don't believe there is any reason not to believe that the diagram above is not correct.

    Having said that it can be clearly seen that there is ZERO control ECU wise with the GPF its all BS

    That appears to be the case, so you may be able to replace the rear silencer and GPF with a valved system and maybe not have any CELs?

    I wonder why Ferrari went with no silencers on the Roma but kept them on the F8? You would think the F8 is supposed to be the more aggressive sounding car given its place in the sports car lineup rather than the GT lineup? Maybe they dumbed it down on purpose to ensure the SF90 would produce a more aggressive sound?

    I think the answer is this. They deleted the resonators, but not the actual mufflers. The F8 does not have resonators. I peaked in under the Roma, and there's definitely a box. The GPF is up front so it was not that. Sometimes dealers will say the oddest things to make things more attractive. If they on purpose did something to make the F8 sound less aggressive, why the hotpipe, and why on earth then not make the entry level car that is supposed to be less frightning even quieter? I've heard them both and to say that the F8 is less aggressive and more quiet is B.S.

    Just got off the phone with a Novitec North America rep and he claims you will have to use the Techtronic plug with the valved exhaust to keep the CELs away...

    Sounds like the typical dealer sales pitch. I haven’t heard the Roma in person yet so I’ll take your word for it.

    So both Capristo and novitec both stating they don't throw a cel. Well IMO just having control of the valve shouldn't. Cel wil depend if you change the cats and to what level. Ive seen 200 not affect cel but 100 and decat do hence why they put extensions on the O2 sensor bung and state you need a tune.

    My opinion is that all the companies that have valve control you wont get a cel. Also going buy the diagrams You can do what you want like a 488 GTB or Pista.

    I should’ve checked here before asking the dealer to unplug the lines basically right after taking delivery. Never had issues doing this on my other Ferraris but sure enough CEL came on after 80 miles of driving. Sound was SO unbelievably disappointing without the valves open that it is difficult to describe. And conversely improved to a very happy place with them open. My dealer has always done right by me and they are looking into solutions. Anyone have issues w Capristo yet? Any input much appreciated.
