I can definitely notice that over all the exhaust is slightly louder in Tour, louder still in Sport, and a good bit louder in Track.
Definitely, a more noticeable difference between the modes.

I did the GMPP CAI/Cold Air Industries CAI - it definitely made both intake and exhaust slightly louder and slightly deeper. I did NOT have a soundtube from the factory, I do have NPP.
