So had K&N s put on my 981 GTS today, initial drive home led me to believe their was less induction noise than OEM filters ???

Interesting, I wonder if there is a membrane or flap in the GTS sound symposer that is tuned to a narrow band of pressure and the K&N is just outside that range.

Pity there isn't an adjustable volume button on the GTS Sound Symposer, or can you hack this ?
