812 GTS too quiet / Novitec exhaust in stock anywhere?

    I for one would appreciate the feedback of many GTS owners. Mine is here is 3-4 weeks. The opinions are so scattered and sound is very subjective. I heard the car in person and it seemed fairly loud.

    After reading many posts, it seems after 2000 kms or so the sound does improve dramatically. Also the sound is described as a more a deeper base vs an older F1 racer “shriek”.

    I’m hesitant to have a CEL delete as this will
    Mask a potential problem that could be very costly and damaging.

    Any input would be appreciated. Or I can just wait a few weeks. Lol.

    To clarify, the modules that cancel the warning lights focus specifically on that error code (e.g. catalytic converters, GPF). They don't cancel all warning lights. As such, I see minimal risk of masking any broader engine problems. For what it's worth, I have used Novitec modules in both my 812 SF and now GTS to cancel relevant warning lights and have had zero issues.

    Yes, the GTS does get materially louder after around 1000 miles (I presume as the GPF burns off / beds in). Even once bedded in, it is a more bassy rumble than the high pitched scream of the 812 SF. Whether or not you like that is of course subjective. I found it to be too quiet (especially at low & mid revs) and I missed the scream, hence my mods (high flow cats to replace GPF plus X pipe and Novi rears). Very happy now - the roof down sound above 6k revs is epic!

    Before the 599 generation it was very common to put exhausts on Ferraris. Have a look at all the 550s/ 575s with Tubi exhausts... Then the factory got better and better at giving the sound many people found pleasing and still complied with regulations. The peak for this sound is the F12tdf. And yet, there are members here who think this car sounds too quiet and tame... I don’t argue with them because that is their opinion, and we should respect that. I bring it up because there is no doubt these new filters, which are there only because of regulations, do make the car more quiet. Maybe it still sounds very good, but there will be some who want more sound and there are options for those people, which is really just a return to what was done in the past. I’m sure there are ways to handle the legalities in each area, but, this is a case where everyone will have a different comfort level. Based upon what I know (and there is probably plenty I don’t!!) I would not be uncomfortable doing an exhaust. Especially from a company such as Novitec which has a track record of being fairly conservative. Sure they are expensive, but I’ve never had a problem with anything from them. As they say, you get what you pay for.

    Very curious to see results!

    Is your car over 1000 miles yet? It is well known there is a bedding time before increased volume

    Has like 100 miles!! But, in terms of sound, I am comparing to similar mile 812 SFs and other exotics I own with similar miles. Maybe it'll get better. I will measure sound now and also before I switch to Novitec which comes in 6-8 weeks [and so I will have many more miles by then].

    It seems the OP isn’t the only person who thinks it’s quiet.

    FWIW, I just drove my TDF for the first time with full Novitec exhaust and it is simply fantastic, how the TDF should have been offered from Ferrari. It is very loud. But with the valve switch, like a 488 quiet when desired. The only other car I've experienced that is louder/pops is the Performante S.
    Why Novi? Given the price of the car I wanted what is considered the best, with exceptional support and backing, and the sound/quality is very good.
    In a used 812 I might have made other choices.
    FWIW, a full exhaust 812 @ the shop was deemed louder than a full setup TDF.
    I am sure you will love your upgrade!

    There are no pending US regulations that require a GPF...it's all about EU and China. In some countries with extra amounts of sulfur (in the fuel) such as Australia, GPFs will get clogged and cause a lot of problems

    Great video. In the written component he said it was quiet with the roof up, but if it were up to him he wouldn't make any louder. Let's keep in mind the 1k bed in time for gpf plus exhuast valves make a difference.

    I'm on the fence with what I want to do with mine when it arrives. Definitely getting a valve remote, but beyond that, I'm going to wait and see. I only plan to drive it with top down, have other coupes for when weather is not ideal

    I love the sound of my GTS as is. For me, a few extra decibels isn't worth the extra scrutiny at the annuals. If you want louder, roll down the back window, if you want even more volume put the roof down. It's pretty loud, the sound quality is great, and it harkens back to the traditional V12 Ferraris of old.

    When driving it’s so quiet with the windows and/or top down that it’s almost hard to hear it at all. Just is...I understand people not wanting to admit it but even my 458 sounds better. About to be fixed though! That V12 will be allowed to howl!

    I don't know what's going on with your car, my GTS is not quiet. It doesn't scream at 9K like the SF but it is not quiet. Of course, your 458 sounds better to you. My speciale sounds better to me...but then again it sounds better than the SF too.

    The V12 should sound better than the V8 to me and mine will with the Novitec. Nothing is wrong with my car other than the GPF - it sounds just like the other new GTS's at the dealer. I will do some decibel meter testing soon, though I'm sure everything will still insist their car is louder to make themselves feel better LOL

    Is is amazing how this issue goes on and on. It is impossible to predict based on sound meter levels what is good sound or bad sound let alone volume unless the meter measures the entire spectrum of human hearing( which varies from person to person and declines with age and/or hearing loss due to damage). In the hifi community the argument of subjective vs objective has raged on for 70+ years. Ferrari has been better at engineering good sound(whatever that is) than most rivals. That of course can change but I expect them to continue to pursue the maximum allowable by law. I will chime in with more when my GTS arrives in 6 weeks or so and I can compare it to my SF under the same conditions. It will be purely subjective I assure you!
    As for the exhaust mods- if someone can show a power increase with them on a dyno I would be more inclined to do it

    Which is all the more annoying for new car buyers in the US, we don't want the trash that EU bureaucrats force the cars in Europe to have. It's too bad that Ferrari doesn't adjust the configuration for the market, especially since the US is a large market for them and to most people the GPF clearly reduces the amount and quality of sound the car produces.

    Sound is the most obvious difference.

    However, the GPF devices have several other negative, more long term, consequences.

    GPF review:

    (x) adds HEAT SOAK to engine bay, did Ferrari do anything to reduce the heat? unlikely, needs to be there for GPF to function

    (x) removes high frequencies from upper RPM so 7000rpm "pitch" is hardly distinguishable from 9000rpm pitch (without hot tube such as on F8/SF90)

    (x) adds COMPLEXITY, it has to burn off soot, it is an 'active device' unlike catalysts

    (x) POISONS the engine, by the ECU forcing the engine to run lean to increase exhaust gas temperatures to do full soot/regenerate cycle

    (x) REDUCES horsepower by a fixed amount, at least 20PS (yes, catalysts also do this, just another negative, that's why listed last here)

    I believe none of that is any good, hence the significance of GPF discussion in discussions....

    I wonder if you removed the GPF will the ECU adapt and not run the engine as lean or do you need a tune? I know there are ODB plug ins that get rid of the check engine code.

    ECU will adapt. No tune required. I know this from experience. I am the paranoid type and after I did my modification (sports cats to replace GPF) I took it to a Ferrari specialist. They checked the emissions and confirmed engine runs completely as expected. This gave me comfort that I was not risking any long term engine / reliability issues.

    And yes, you need the OBD module to avoid error codes.
