I have a 2019 Svart 701 and an Arrow decat. The bracket works just fine but it needed a slight modificaition to one of the sections – I had to grind a slight half-moon, about 1/2″ deep, into one of the upper cross sections to avoid making contact with the exhaust downpipe.
It fit without the mod, but made contact.
If you have a straight decat section, you can fit this without an issue except the one noted above. If you have a larger, bulged, midpipe, you might not unless it is an Arrow, which I know will fit.
