My twin Arrows don´t have spark arrestors, but that´s something the European authorities don´t seem to have come up with yet. I´ve been checked by the traffic police here twice and they were satisfied when they saw the Husqvarna stamp on the two mufflers.
Good thing they don't care about all this mess where I live. All they care about is that you're insured, registered and have a motorcycle endorsement on your driver's license.
That's what I did; it takes a couple of minutes with an Allen wrench and you can't even see it on the back side.
Did you flatten out the projecting tabs on the bottom? I was afraid they would wear through the titanium muffler shhet metal if inverted. guess I can dremel those flat, is likely what I will do.
I can't remember, but it's been turned around like that for a long time and nothing bad has happened.
