    Many thanks for that.
    It happens in both stock and open valves mode. Obviously it is a lot more noticeable when the valves are open. If you’re not getting the same issue, then it may be the Capristo mufflers at fault.
    In your setup, do you get a high pitched howl in the higher revs?

    At full throttle/high revs it doesn't have quite the sound of a normally aspirated Ferrari,but I would still call it that "ripping silk" sound that characterizes Ferraris. Whatever it is,I love it. Tubi mufflers don't do a lot of muffling:

    Thanks. Much appreciated.
    Sorry for the ignorance. Are you saying that the “ripping silk” sound is because of the x pipe or the mufflers? If it is the mufflers, then please could you tell me what advantage the x pipe is giving you?

    It’s just that it will help me to decide on how best to proceed. For example, I could try sticking with the capristo mufflers but remove the x pipe and re install the stock H-pipe. Do you think this would help?

    The full stock factory exhaust system was very disappointing sound wise.

    According to something I read last year,the switch from an h-pipe to an x-pipe mainly produces a higher-pitched sound. All my exhaust parts went on at the same time,so I can't say what they would do separately. Putting the h-pipe back in should be a lot easier than changing mufflers,but I can't say what the result would be.

    An X pipe always produces a smoother and higher pitched sound than an H pipe. This has been the case and known as long as dual pipes and crossovers have been around. Personally I think the H sounds much more natural and better on a flat plane V8. The X gets very thin, and while it can get loud, it lacks body and energy. Back when the Cali was n/a and new, Capristo offered both an X and H version, and the H was the one to have imo. The X was high pitched, but like an IPE sound, incredibly artificial and synthetic.

    I have been on this forum for over eight years,and one thing I have learned is that what constitutes an enjoyable exhaust sound is highly subjective. There are many discussions/arguments here about what changes to make and which brand of components to use for each model of Ferrari.

    Try 100 or 200 cell sport cats, they will make big difference. But never expect high pitched formula 1 type sound on a turbo charged V8. You need a NA V12 such as F12 or 812 SF to make this kind of sound.

    True. The turbo matters a lot, and the long exhaust tubes aren't helping either. Even with 100 cell cats, it still won't be very high pitched.
    The best recipe for anything remotely close, is a full decatted system. This is what I'd do if a high pitch sound was the goal.
    Kline inconel decat pipes
    Kline inconel X pipe
    Novitec inconel rear section w. flaps.

    The material has an effect on sound. The inconel creates a sound that is slightly sharper an d more "crispy". A shame no one offers a titanium system.

    Now all this is fine, but mind you. It will be a loud mother, and decatted cars smell. Will it remove the drone? Perhaps. Others have mentioned that the Capristo boxes can be drony.

    Just out of interest, did you ever get to try the combination of Kline downpipes, stock h pipe and capristo mufflers? If so, what was the result like?

    I am still trying to work out which combination to go for. Currently I have the Kline X-pipe and capristo mufflers - however with the annoying drone. Reading the latest replies, it seems that I am unlikely to het a high pitched sound on the portofino. That leaves me wondering what exactly my X-pipe is doing? Should I have just gone for the Capristo mufflers alone?

    There is also mention of installing 100/200 cell cats - what effect exactly would this have over the capristo mufflers alone? Is it purely volume or also character of sound?

    Thanks.

    This afternoon I made a point of driving in city areas in Automatic and being in the 1500-2000 rpm range. I did not notice any drone in Open or Stock mode.

    Several months ago the Atlantic magazine had an article about how the cooling systems at server farms make a humming sound that most people in the area don't even notice but some people find maddening.

    No i did not try that combination. I'm very much pleased with Kline downpipes + X-pipe and stock muffler. The sound is loud at low rpm and gets high pitched over 5K rpm. I have a stock 458 and i think the sound of the Portofino can reach 80% of 458's loudness.

    X pipe, it can increase the pitch but won't help much if you don't change the downpipes.
    Downpipes will allow more exhaust flow and increase volume.
    Mufflers, i'm qutie sure what it does......

    Kline is developing the rear section and hope they can finish up soon. The price of Novitec parts are just ridiculous.

    Thanks for all the advice on this forum - it's been great.
    Does anyone have a comparison of the Capristo vs Tubistyle mufflers for the portofino? Is there much to choose from between the two?
    Also does Tubistyle have any kind of remote control valve control like the Capristo system?

    With Tubi mufflers the stock valves are transferred to the new mufflers and the valves operate the same. If you have a Capristo E2E controller then it operates the valves on the Tubis just like it operates the valves on the stock mufflers. Capristo mufflers use their own valves which are vacuum-operated like the ones on the Californias. You have to run a vacuum line to the engine compartment for the Capristo valves. Capristo makes a different controller that is for their own mufflers.

    Hello everyone.

    Just thought I would share my experiences over the last few months with the Portofino exhaust.

    After having taken advice from plenty of people, I tried various combinations of Capristo mufflers, X-pipes etc.

    I can confidently say that in hindsight it was not worth making changes to the stock mufflers. Apart from the ability to open and close the valves with a remote control - the sound was not significantly better.

    The middle H-pipe certainly should not be changed as this has a anti-resonance filter that stops any droning. (The X-pipe I initially tried caused lots of droning).

    Finally. The only thing that made a significant difference (and also pleasing to the ears) was to change the cats to 100 cell Kline sports cats. Wow. The difference is amazing and will give you a lot more enjoyment from the car.

    Obviously, it will be never sound as sweet as a naturally aspirated engine - but it’s the best option for the Portofino at present.

    Hope this is useful to someone.

    Thank you for sharing your experiences with us. I very much agree with you that stock mufflers are the best. But i also have X pipe with not drone at all. I have 200 cell cats + X pipe + stock mufflers and the sound of this combination is excellent. Last month i tried Tubi mufflers with 200 cell cats and X pipe, but the drone at 2200 rpm is unbearable even with valves closed just like Capristo mufflers.

    Anyway, do you get CEL by using 100 cell cats?

    Hi there.

    The dealership installed a Capristo OBD module that cancels any CEL warning light.

    That’s quite interesting about the x pipe. I just wish I knew what kind of difference it would make in addition to the sports cats. I may consider it again in the future. But the dealership did not even entertain the idea!

    Secondly I was given the option of 100 cell or 200 cell cats. Both were the same price. The dealership suggested the 100 cell ones based on their own experience. I assume the only difference between the two would be volume? If so - any idea what that difference actually is in quantifiable terms?

    I have the Capristo module as well. It works fine but i wish there could be a solution that could stop the CEL forever.

    For X pipe, i was told that it can increase the pitch.

    I agree that the only difference between 100 and 200 cell cats is volume. The reason i chose 200 cell cats in the first place was i hoped they could have better catalyze effect to avoid CEL but they simply didn't. :<

    The flash that I got from VR Tuned ended the CEL and other electronic warnings as well as providing a big power increase and no more Stop/Start.

    Hi.

    I would love to go for this option. But my only concern is that it will invalidate my warranty.

    That start/stop is certainly annoying. Even though you can switch it off with a button, it is an unnecessary step!

    This sounds charming. But will it void the warranty?
