I'm sure the answers are in the 209 pages of this thread, but my head hurts from trying to find the answers
I'm just trying to figure out which one is right for my '12 R1200 GS/A (IICE Air, IICE Cool, and IICE Smooth) or what combination for a full exhaust.
Again, sorry if it has been answered before. I even looked for a FAQ. Thanks!
