    Hi everyone,

    Could someone tell me how much of a difference in sound quality, an aftermarket system makes to the 488?

    I have a 488 with the valves always open. It sounds better than standard because it's louder but the sound - in my opinion - is absolutely awful due to the tone. This is especially the case below 5,000rpm. I had an F12 with an IPE system and also a GT3RS with a sports muffler so perhaps I've been spoiled.

    From my research, unplugging the valves effectively makes it straight pipe anyway so I'm wondering if there is much of a difference even if I upgrade to a proper system. I would be only looking to replace the rear box. Any information on this will be greatly appreciated.

    It is not straight piped when they are opened - it is divided. On top of that there are other design elements that matter, such as the crossover between the banks etc.

    This is a car fitted with a Novi box and stock cats.

    Cant really comment on the decibel levels since I put catless mids in. But I do know my catback is an X pipe and titanium. It would certainly have a different pitch compared to stock with the valves up.

    Thanks guys. I really would like to improve the sound and was worried it would sound very similar even with an upgrade!

    I strongly recommend going with an aftermarket system. I replaced my OEM exhaust with a Novitec system, then added Fabspeed sport cats and charge pipes. Took car to my dealer for annual checkup and the techs literally told me it's the best sounding 488 they've ever heard. Worth every penny, especially during tunnel runs :)

    I'm thinking about the same setup, as Novitec only has 100cel HFCs. Any vids?

    Could someone help educate me?

    On the stock exhaust is there any valve opening and closing control? I thought they were just always open?

    There is an OEM option for sport exhaust. Is that just for the black tips? Any other differences?

    Sport exhaust is just the tips.
    Capristo or Forza make a plug in module use you with a remote to open and close the valves
    On a 488GTB the valves are closed until around 3krpm in wet and spirt mode or around 280prpm in race mod. They open up above those rpm.

    on my 488 I just unplug the vacuum hose to the valves and plugged the. Car sounds better under 3k rpm and the same above. A cat back x pile sounds good too some differences in sound but the real sound comes when you do cat delete. However then you need a tune for the car to run correctly and give you check engine light…thus your warranty on anything the ECU controls is voided.
