Fishtail mods forum has wealth of information!! I’ll be getting my 2022 R18 719 in a few weeks. I can’t stand the long fishtail mufflers until saw the shortened version. It’s a dramatic change! If I shortened them w/o altering the internals such as confusing the program, leaving the flapper open, or drilling baffles, or taking them out, do I need the stage 2 to keep it running right? Would simply shortening the mufflers void the warranty?https://cdn.shopify.com/s/files/1/0...Application_Chart_12-15-2021.pdf?v=1639664492
Scroll down to find the BMW R18()
They are the same.
