Those do look stock!
Mine felt different after the first service. Besides the additional RPM allowed, shift was way smoother.
I only had a chance for a couple short rides with pipes and a map, and this all while trying (sorta) to keep my run-in rpms in check. Hard to tell for me. The sound, on the other hand...!!
Hopefully will get her back this coming week!
Edit: I felt the same as you regarding the baffles. However... Have you taken them out and gone for a ride at all?
I could not believe the sound! Like an old V8 muscle car!
