I have heard from a Tenere owner who has an Akrapovic system that the system supplied by Yamaha does have the catalysts installed but the system ordered elsewhere (non Yamaha dealer) does not have the catalysts installed in the bellows before each muffler.
Push comes to shove, I guess you could use a dremel to open the seams of each bellows, remove the cats and re-tig it back together.....
