    6-1 Headers, 200 cell cats, & center H pipe from Fabio ********** & Tubi. Mufflers. It is exactly the sound I was hoping to achieve. I tried without center section first, and it was still too quiet. It is perfect now and I could drive it across the county as there is no drone or anthing. Docile under 4k revs

    Did your 575 have the factory center resonator or was it a later car (Assembly number 51797+)?

    Do you happen to know which Tubis you have? My “competition” Tubis sound much raspier, though I am not running cats and it may just be from increased airflow.

    I actually have no idea which tubis are in there. I will say that I was going for a specific sound and I started with just headers and 200cel cats and it made a very subtle difference, but once I put the center h pipe from Fabio in, it was exactly the note I was after. I absolutely love it now. My dog can fall asleep on road trips and there is no drone or resonance. and when the revs are norht of 4 it sounds perfect to me.

    That’s awesome and agreed, it sounds perfect! If you get a chance, stick a camera under one of the mufflers for a pic.

    Not a 550, but on my '95 456GT. I had previously installed the Braden straight pipes eliminating the resonator, then found a set of Tubi's. I just did the clutch in it, so when re-installing the exhaust I put in the a set of Front 2-1 Euro pipes eliminating the catalytic converters. It sounds exactly the way a V12 should now, so good!!

    If you have PM's, shoot me one, I couldn't find it on your profile. Have you attempted to fit 550 manifolds on a 575 or 575 secondary cats on a 550? The secondary cats look identical even though they have different part numbers (different cat construction?).

    No, I have not tried 550 manifolds. Fabio is building me a 6-1 exhaust as we speak. Those are not the secondary cats, they are the primary cats. The secondary cat language is a marketing ploy by aftermarket exhaust sellers trying to get owners to go with just the precats and eliminate the primary cats. The pre-cats are designed to get everything up to temperature rapidly and cleaning before the primary cats warm up and start doing their job. Later cars with more efficient ignition/injection systems and better catalysts do not need the precats and only have one or two primary cats.

    I do not take PMs (conversations) because I get asked questions I am not qualified to answer.

    Good to know about PM.

    Thanks for clarifying. I referenced first/second as their location downstream from the engine. The 550 likely has a different cat since its the only cat vs. the 575 secondary hence the different part number. But physically they look very similar. Fabio headers will be a nice upgrade.

    In Germany every 2 years we have a technical check which includes an emission check also.

    Today I had the first emissions check with Fabio's 6-1 headers and cats, I installed them autumn 2018.

    Result :
    Excellent emissions !
    So the cats works fine.

    Drove home at the German Autobahn (highway with no speed limit).
    Man, this machine pulls.

    ;)

    Daniel- Not too long before I get to try them out. Give me a month or so.

    I saw that you ordered them.
    :)

    You will bring your 575 into a new sphere.
    And you will have regrets that you haven't ordered them earlier.

    With the corona situation, I have to wait some time before I will get the system for my 599 GTB.

    Please report when you have installed the system.

    Definitely would love to hear a before and after clip ! I have Fabio’s Double H pipe on now and his Muffler Deletes shipped just a few days ago.

    His 456M headers are on my wishlist.
