812 without GPF or with? Is there power difference?

    I don't think Porsche is installing GPF on US-spec cars, only on Euro-spec cars.

    It's not just a matter of removing GPF. It's also a complete reprogram of the ECU.

    Thereby voiding the OEM warranty I presume.

    Yes. And in Europe, if you're caught removing OE-installed GPF, you go to jail.

    He's saying Porsche themselves don't fit GPF to US cars, and thus, they likely use a different ECU tune. Thus, their warranty should remain intact since it is the manufacturer making the adjustment. However, my Porsche friends all tell me the US versions of these cars still sound bad and they say its because Porsche has some how engineered in the same sound and engine response as the GPF cars...??? Very strange if correct.

    Why would Porsche engineer the same crap sound in non-GPF vehicles if they weren't forced to? The high pitched wail of my GT3 is one of it's most endearing traits.

    I'll second that - especially with Sharkwerks exhaust. :)

    Apparently Porsche is trying to mimic the back pressure from the GPF and my friends who are into all things Porsche say the cars don't sound good and they are baffled why Porsche would do this. Sorry, I can't explain it better.

    That’s absurd. I have a 2019 US GT3RS with no GPF and it sounds bad a**.

    Just an assumption - they may have the exhaust without GPF replicating the one with GPF (e.g. to get the same back pressure as mentioned) so that they have exactly the same ECU configuration in both versions.

    My 812GTS will have GPF....I'll tolerate it throughout the warranty period. If there are proven reliable solutions by the end of warranty from the wiz-kids at Novitec and others...then I will pull it off and a new car will be reborn!

    He says its on 2020 models. I'm not a Porsche guy so I am only going based on what he says.

    This would be sensible. But then, what's the point in not including it?

    Please provide some support for your assertion that removing GPF can result in a custodial sentence.

    Hi,
    Any information if GPF will be installed in the USA?

    Not easily, and not without voiding the warranty. I'm sure the usual suspects will release a GPF delete down the line, but it is not there yet.

    FYI - I spoke to a dealer in Sydney yesterday who had had the car there for a while.

    He confirmed the GPF unit is fitted between the headers and the cats. My concern is that it will be virtually built into the engine and thus harder to remove (unlike an installation further downstream, say after the cats, which I think is easier to take out)

    Not concerned about power. But about sound. Has anyone listened to the 812 GTS?

    I posted a youtube video (search '812 GTS rev') which was taken by a dealership in Sydney (which I spoke to). However, it's hard to tell from the video how 'good' it sounds, especially since it was shot indoors. It doesn't sound terrible and quiet like an F8, but to me it sounds different (and I own an 812).

    For what it's worth, the Ferrari sales guy said they sounded very similar (812 and GTS). I did mention to him when we first spoke that I'd already ordered the GTS so no need for the sales pitch, hoping to elicit a (more) honest response.

    Seems like a few GTSs are trickling out into the public / demonstrator models now so I'm sure it won't be long before a F chatter or you-tube reviewer gets their hands on one. If anyone can do (and film!) a side-by-side comparison of an 812 and a GTS (both with stock exhaust) they would become an instant hero!!

    I listened to a 2020 812SF in the flesh yesterday (Nov. '19 build) and the exhaust note, at start-up, idle to rev scream, sounded identical to my '19 SF. It's possible that GPF is installed starting with 2020 *build* dates. That info I don't have.

    I highly doubt an 812SF which has been delivered at this point, will have a GPF. That being said, I just asked a rep that just heard a GTS in the flesh, and to quote him. "I can't tell the difference, it's as pissed off as it ever was - I'm impressed". This guy is a car geek, and he does not pull punches. I've witnessed him in the middle of a showroom talking openly about his dislike for the FF sound compared to the F12 and Lusso, and continued into his displeasure about the added softness about the Lusso vs. FF. The man speaks his mind lol.

    Did the 812 GTS have GPF? Early models may not. Thanks.

    All and every GTS have a GPF as far as I am aware. But to answer your question. Yes, this one had GPF.
