Would removing PAIR system increase stink?

I've only had my 2007 919 over a month now but have tinkered with the exhaust and PAIR system already.
As soon as I did the bafflectomy I heard the deceleration popping so I did the PAIR mod. I don't recall noticing the stink pre-bafflectomy.
From what I've read it seems the PAIR system if you leave the stock exhaust alone would help reduce stink.

I've got a stock set of exhausts that have not been messed with yet and I'm thinking of putting them back on as well as PAIR system.
Thoughts or comments?

PAIRS injects fresh air. It shouldn't increase stink in my opinion.

if you love your motorcycle, set it free.. if it comes back and hits you.. you highsided

Yeah, that's what I mean. It seems to be it would help leaving the PAIR system in place because it reduces stink by injecting fresh air.

You'll get stink no matter what if you keep the high exhaust profile of the 919. It's the vortex created behind the rider that pulls exhaust back towards you as you ride.

PAIR won't help either way (if you've already taken it off, just leave it off) and a bafflectomy does change backpressure slightly, but not as much as a full slip-on exhaust.

The only true way to remove most if not all stink from riding is to do a 900rr low-mount exhaust.
