Swapping 2019 exhaust onto 2020

    Hey guys. New to the forums. Just picked up my 2020 Svartpilen 401 a week ago and I’m loving it so far. One change for ‘20 that really disappointed was the rerouting of the exhaust under the bike.
    I found a complete 18/19 exhaust on eBay for $120 so I pulled the trigger. I am installing it right now but I know there’s a few extra tubes and hoses in the way. I was wondering if anyone with an ‘18 or ‘19 could share some photos of where the evap canister hoses are routed.


    The lower evap hose goes to a Y and I can see the vent hose off the bottom of the Y is still on the left side of the bike, but I’m not sure where the hose going up to the tank is routed.

    The upper hose off the evap goes to a sensor that is mounted right above where the exhaust should go through. I believe it’s somewhere else on the ‘18/‘19. But I have no idea where that one goes.

    Also there is a coolant hose Y connection on the right side. One of the top Y hoses goes to the coolant reservoir, and again the bottom is an overflow off the right side of the bike but the other connection at the top of the Y crosses over to the left under the airbox where the exhaust would go. Any help on that would be appreciated!

    Thanks in advance! and ride safe.


    I think I’ve figured out the coolant hose, looked at a couple right side photos and managed to deduce where that one runs.

    it also looks like the upper hose off of the Evap canister Y union goes back up and around the shock, or back up into the under seat area, can anyone confirm?


    also it looks like the upper evap hose just runs straight along the left side of the bike and I don’t see a sensor. Maybe the update to the 2020’s was adding that?


    Any confirmation on these 2 issues is greatly appreciated!

    How did it work out?

    More info on this? Pictures?

    I’m considering the same thing!


    Interested too I hate the relocation and I don’t understand why the vatpilen has it passing inside!

    2020 Vitpilen also has it passing underneath. I suspect this is due to the additional catalyst in the 2020 exhaust: meaning the 2019 exhaust does not meet new emissions somewhere in the world, likely California, which not only has endemic smog issues and therefore the strictest emission standards, but is also one of the largest motorcycle markets in the western world.


    Someone mentioned on here that the exhaust passing through the frame caused concerns to the Husqvarna engineers about overheating the parts of the ignition and/or fuel injection system that were located near to the exhaust.

    Isn’t California one of the few US states that allows motorcycle lane filtering?


    Also agree with the frame routing being better and safer if you ask me. I live in Central America and we dont have that emissions issues with ours machines. I have a 2019 model that has the frame routing. Also added a full racing pipe from GPR, took out everything, lol. The sound is amazing.
