Currently have the standard Honda silencer, but would like to beef up/deepen the sound.

Any idea if a Viper/Scorpion can would be ok on a trackday with a standard airbox?

If your selling something suitable - give me shout

Pretty sure bike cans struggle on track day noise tests.

Big problem On BEC,s is making them quiet for tracks. So a great sound and quiet enough are contradictory.
I run a scorpion can and I doubt they,d let me in th paddock!
So a std can is a good plan for track and mot and swap for a nice boomy one for the road
