    Just finished putting on exhaust on friends 458. This car's running path is really short so not much you can do in the routing sense. We did an X cross like all exhausts but it seems quiet to me. Even the car with no exhaust at all seemed quiet. I just noticed a lot of these exhausts available are running test pipes. Now I'm thinking that's what's blocking the F1 pitch. On 04-08 Gallardo you can get a little high pitch on stock cats. Test pipes puts you in another league.So anyone running stock cats and get actual high pitch note with just exhaust?

    To get the high pitch tone you have to take the cats off,

    Cat off makes louder. To get high pitch, you'd need novitec's muffler. Then just get it completed with header as well (Fabspeed is very good, but legend says Novitec's inconel even louder). Make sure you get muffler with flap, so f*$kin neighbours won't knock at your door.

    Somewhat disagree, just straight pipe it and you will get the high pitch tone,
    even if you leave all other parts stock, provided the exhaust valves are constantly
    open via an exhaust valve controller or by simply pulling the wires.

    However agree with mik that the straight pipe Novitec system, incl.
    aftermarket headers is a great way to go, here is an Italia with Novitec
    straight pipes, muffler, Fabspeed headers and EVOSmit tune:

    Along with RSM's 458 Spider snd my car it is one of the best Italias
    I have ever heard

    Sportscats can help with a higher pitch sound, but it all depends on the headers and mufflers to get the "F1" sound. You need equal length headers with an exhaust tuned for that sound. You have to remember that the engine itself does not produce that sound as it is not an F1 engine revving to 18k, hence it has to be created artificially by amplifying some harmonics and remove others etc.

    IPE makes a complete system for this where you get a set of headers and a cat-back system. You can amplify the effect by installing sportscats or test pipes, but the sound itself is created mostly in the muffler and partly the headers. Equal length headers will usually also increase volume a tiny bit. If you really want an exhaust with a high pitch raw scream and that is loud, the IPE Titanium F1 combined with their headers or Novitec Inconel headers is what you want.

    So in essence if your buddies system was not designed specifically for the F1 sound in the first place, it's not really possible.

    Respectfully disagree, the F1ish sound is always there but the stock cats muffle it,
    all you need to do is straight pipe it to get it, even leaving all other parts stock.

    Aftermarket mufflers, headers, air filters, tunes, etc.. do little to the sound,
    albeit perhaps modifying its' tone and increasing volume a bit.

    The stock cats are the most restrictive when it comes to sound and replacing
    them with high flow units or straight pipes is in essence all you need to do
    to get the high pitch F1.

    Heads up: you may get a Check Engine Light by tinkering with the stock cats.
    Some cars are more tolerant and forgiving than others.
    Although there are several ways to effectively deleting CELs from the dash, the
    fault code will be still recorded in the OBD even if it has been temporarily deleted on the
    dash by anti-CEL units and you will not pass smog inspections if you leave in an area that
    requires it unless you revert back to the stock cats and perform a drive cycle to reset all
    the monitors of the OBD; save opting for other solutions.

    Fwiw here is an old video of my car with 100% all stock parts (albeit running 100aki):
    F1ish sound is already partially there, it is a trademark of the engine:
    https://www.youtube.com/watch?v=JWc2AdErGco

    Here is newer footage of mine with GMG 200 cell cats, Innotech f1 SS headers, sport muffler,
    bmc air filter, as you can hear the sound is quite arrogant but less high pitch, or shrill
    than in the straight piped white Italia above:
    https://www.youtube.com/watch?v=eQbXRJwiSPQ
    https://www.youtube.com/watch?v=vG-OaBbKBFk

    The reason why I opted to keep the cats is to give more body to the sound as imho the
    decatted setup looses some lower frequency from the lack of resonance provided by the body
    of the cats and, although dramatic in the high end, is a bit thin when heard in the flesh,
    also the GMG cats pop like crazy so they are def keepers :D

    I ever been on a track with another 458 with IPE exhaust, but I didn't know if that was cat less or sport cat, my full Novitec was louder and screamed much higher. Actually I was banned because of being too loud. Right after the first lap, the track manager told me to upshift at 5,000 rpm max, and avoid downshifts. That day became a car parade instead of track day.
    Novitec's sound scary from far, it's like a race car going very fast towards you. But it's very hard to judge from a video. In real it sounds much louder than the video. RJM ran his inconel novitec under the bridge, that's like half tunnel. But I can't stand the loudness going into tunnel with roof opened. My ears kept ringing for 30 minutes after coming out from the tunnel.
    When modifying exhaust, just make sure you get the flap, the cold start is almost as loud as stock 458 with half throttle rev, some more the sound is very annoying because the engine gives little constant rev to warm up. Neighbors will ring your bell very soon.

    I agree with you 100% you don't need other headers for the high pitch sound. I'm fairly new to Ferrari chassis so I wasn't sure if the stock cats were THAT restrictive which is why I posted.

    The sound comes from it being an even firing engine.Cars like a Corvette are odd firing order,no matter what you do it will always sound like a muscle car.This is also why the Viper V10 sounds nothingggg like a Lambo v10 pre 2009 which is when they switched to odd fire. There went the high pitch exhausts everyone liked.

    Anyways I did some more test driving and car for sure isn't loud enough as we expected it. I don't have time to do cat deletes so I will put that off till another time. One thing I did noticed which may be good or bad depending on who you ask. The car breaks the tires loose on a lot of the shifts. I wish we had did a dyno on this. It wasn't spinning them like this before.

    Thx for the info and feedback.

    Is your 458 an early year? If so this explains the tires spinning, esp. from 1st to 2nd, my 2010
    always does this except when the tires are brand new, even with all the nannies on.
    Gotta be careful and apply throttle very carefully up to 3rd gear, at least in my car.
    Ferrari really made incredible improvements with subsequent e-diff generations, the Speciale's
    traction is incredible and the 488's stellar, as a matter of fact the e-diff is pretty much
    the only think I like in the GTB: it is truly out of this world!

    +1!!!! One of the most epic sounding Italias ever!!!!

    Unfortunately the car has since been sold and I reckon returned to stock
    after its' ecu being updated by the dealer unbeknownst to the ex-owner :(

    There are a number of combinations that can get you that F1 howl, but as mentioned, it usually requires upgrading the stock cats to something a bit less restrictive.

    My personal favorite combination on the 458 is the Fabspeed Sport Cats and Sport Headers. It's a very well-received setup, and all of the guys I know who run this configuration absolutely swear by it.

    Here are a couple videos from a third party individual who has our cats and headers installed:

    I also attached a few photos so you can see exactly what they look like; they're like works of art! You can also see how massive the factory cat is. Crazy restrictive!

    I hope this isn't common knowledge, but if you (like me) never quite understood flat plane crankshafts (e.g., Ferrari V8s) versus cross plane crankshafts (e.g., Corvettes) and why the engines sound so different, then watch these two videos. There will be a quiz afterwards. LOL
