Looks like they changed the location of the CAT:
But Tony and his cronies in the Screamin’ Eagle department didn’t stop there. They also created a calibration for the 120ST and packed each muffler with catalytic converters instead of the headers to increase flow. “One of the key things of this performance exhaust system is that typically the Touring bikes come with the cat in the header system,” Tony states. “Well, you don’t get as good of flow with the cat in the header system—it’s somewhat restrictive—
so what we did was put the cats in the mufflers, and they’re much bigger at the muffler. We also increased the inlet at the muffler so all of that combined creates much better flow but all still compliant.
Ummm...I wonder how quick the mufflers will be switched out.
