    Akrapovic Evo Full Exhaust (OLD vs NEW)

    Hi Guys,

    I haven't a clear idea on the full exhausts that Akrapovic produce for our Tuono (my '17-'19),
    on their website they only list the Evolution Line (Carbon) with code S-A10E8-RC

    which seems to be compatible only with latest gen Tuono v4 and Rsv4 ('17-'19)

    While on other websites I see the old version of the Evo 2 Exhaust claimed to be compatible with all V4 from '09 till now

    I see only a difference in the silencer shape...is there any other difference (for exhample internal diameter)?
    Can I mount a full Evo2 without care of the precise model or the older ones doesn't fit my bike?

    I rely on you for clarifications.

    You can fit the evo2 but it does not have provision to fit both of your lambda sensors so they need to be removed.
    Both systems require you to use race mapping

    But the new model comes with 2 sockets for Lambda sensor, right?
    So, for a road use with temperature changes, and with standard race map, would be a better choice the Slip-on, (instead of the old evo) to have a proper carb?

    I know that I am not answering the question as you asked it, but in case you are considering a full system in order to eliminate the catalytic converter and flap valve, on 2017+ both are in the muffler, so a slip on will eliminate them both. I installed the Akrapovic slip on on my 2018 Tuono (with Race map, of course), and the difference is very noticeable, much more than on other motorcycles which have the cat in the headers.

    Yes, I knew that, and it's remarkable that you can gain a lot only with the slip-on replacemebt.
    Some say that the OEM exhaust is similar to an Akrapovic Evo (excluded the silencer) but in stainless steel...maybe Gabro knows the real GAP between the slip-on and the full exhaust.
    There is still the question...is it worth to replace the full exhaust (or not) on the latest Tuono?

    I'm running the full EVO II system on my '18 Tuono. The headers are very similar, stock to akra. I don't know how much difference they actually make, but as a street bike I would bet it is next to nothing. I simply like the Ti coloring, and after the purchase price of these bikes...whats a little extra on top for "best of the best" anyway

    streetbs93, the look is gorgeous
    do you have the latest Akrapovic Evo 2? It comes with 2 bungs for lambda sensors or did you excluded one of them?

    This is the latest EVOII and there is only one bung for a wideband sensor. Nothing for the stock lambda sensors; they are unplugged and not needed with the race map.

    Yes they look wonderful, it's a shame you cant get a RH side stand to lean the bike the other way when parked
