Low Boy Map Question

Right all,got the low boy fitted prior to pick up last week 17 plate,looks great but to be honest expected to be able to fit my fist down the end can?? as it was a full race system?
Anyway dealers said they could remove baffle for me if I wanted.... my questions
1.how much louder.
2.is the original map sufficient for performance,don't want it shooting flames etc but there's no cackle/pop on the overrun as it is now,I'd like a bit
I know similar threads been posted but there a little old,thanks

 

Might have to let someone else ride mine so I can hear it better,still running mine in so maybe it'll sound a little different when I really give it some

 

Had baffle removed today at 1st service........sounds awesome....might have to dig my earplugs out evotech levers fitted too,all good to go,lovin this bike more than the s1000r

 

They charged me £96 inc vat for service,change levers and removing baffle
