From everything I’ve seen, there is no difference internally between the mufflers.

The only difference is the outlet where the visible exhaust tips are bolted on.

We can speculate as to why they are different sizes - common guess is you can’t easily swap the tips without some modification.

I have confirmed though, that S tips slide right on to the Non-S muffler.
