    Pair of stainless steel silencers with removable dB-killers.
    100% stainless steel construction, handmade in Italy, fantastic quality.

    These are hand-made to requirement, specifically for your bike. So they fit with no need for brackets/bends, they come in direct replacement of the original items.
    Three finishes to choose from: brushed stainless steel, "mirror effect" polished or ceramic black treatment (autoclave-baked for ultimate aspect and strength).
    - Weight gain: less than 3 kgs per pair, less than half of the original exhausts!
    - Performance gain: around + 5% in torque and power, effect felt in particular at low/medium revs
    - Better heat dissipation
    Noise level 3/10: a little louder than the originals, with a "classic" sound style.
    The dB-killers are removable in a few minutes. Without the dB-killers, the noise is of course higher without being "antisocial" (or getting you into trouble).
    Certification/ECU adjustment
    - for bikes up to 2016, these silencers come with a Euro3 certificate and are therefore road-legal in Europe ; a carb/EFI adjustment is not strictly required (the bike will work fine without it) but it is recommended to gain all the performance benefits of these silencers.
    - for bikes since 2016, the silencers come with a Euro4 certificate and are therefore road-legal in Europe ; There is no need to perform an ECU adjustment, it will automatically adjust itself to maximise the gain in performance.
