Hi, so first post on here but I've been lurking for a little bit.
Bought my '20 Svart 401 in June of last year and have loved it since. Everything about the '20 bikes seems to be an upgrade over the '18-'19 except for the exhaust routing. So I ended up buying some parts from a Duke 390 and swapped over the exhaust.
It's a pretty straight forward process for removal. It took about 30mins to do. Biggest hangup was removing the chamber. The lower mounting point is snug and took a tap with a rubber mallet to release.
Install is a bit more challenging and still need to figure some things out. The charcoal canister solenoid thing needs to be relocated. I ended up tucking this up and behind the rear shock. I'd like to find a more permanent solution to the current one. Possibly make a mount rather than using zipties or see if the one from the 18-19 bikes can be swapped over, doubtful on that. A few rubber lines need to be moved. The one from the canister needs to be moved to the outside of the frame and the drain line needs to be moved infront of the rear brake res. I used cheap Duke 390 muffler from Amazon and it's about 3" too far back. The plan is to drill and tap into the rear footpeg bracket, but I may see what else I can come up with.
Things to note. You'll need an entire exhaust from an 18-19 Duke or Svart/Vit. Nothing swaps over. I used a Compwerks chamber delete and the cheap muffler as previously mentioned. Currently a bit too loud for my liking so if someone with an 18-19 wants to swap their chamber straight up for the chamber delete let me know. The 20s may have a slightly different rear shock geometry. The cat is extremely close to the shock, though when compressed it moves further away.
I'm also going to need to figure out a new skid plate. Bike currently doesn't have one and leaving the original one sort of defeats the purpose of rerouting.
