Bad news

I just had the K&N out to clean and I checked out the air box baffle. Bad news - it's not removable. TTP performance figures for the Breathe are mainly benefited by the airbox baffle removal (IMO) and on investigation their performance figures and baffle removal are all based on a 790 Bonneville.
There is a moulded baffle in our air box with two holes facing the main intakes but it is an inherent part of the air box.
It can only be removed or opened up further by plastic surgery - the invasive kind. Anyone know who has done this and what shape and success they had?
Or I could be brave/rash and start amputating! But it won't be reversible if it worsens performance.

Edit: I will start a new thread on Gutted Air Box to get more readership. But if you have ideas on performance please feel welcome to continue contributing to this thread.
