PowerTRONIC just released the FuelX ECU for the 401!

BUT the problem is it probably will get deathly loud if you change the entire exhaust. A lot of people will go back to using the stock muffler on everything else upgraded because it's quiet.

Oh, they don't talk.... pretty sure you knew that though.

Yeah. I’m not going to remove the cat(s). I had cat delete and open muffler on my Thruxton and the sound was insane. The bike is already loud enough without removing the kidney, so I’ll probably leave that in as well (but I have to admit kidney-delete and lithium battery is tempting).

Life is no fun. We want more power but we want to contain the sound. We can't have both. If we remove all of that and go full exhaust then we can add a big DB killer and wrap it....... then it defeats the airflow again.

I ordered this, an extension to move back the lambda sensor of my vitpilen 2021, I'll try. This should allow the sensor to be lured and increase the proportion of gasoline spread at low and medium rpm
Has anyone ever tried? it's common to do that on car engine or on other bike Euro 5

Then you might as well just eliminate it.

libito? OH, Oxy sensor. I thought you wanted me again!
When you get a header it can create an engine error on some vehicles so extensions are put in. an o2 eliminator probably does the same as our friend above just said.

You should do a mini ride test before and after and let us know. without other upgrades it's pointless though.
