Noisy supersprint track days

[gav]

Ive got a cs, i know its not a csl, but we are from the same family?

Basically, ive got a noisy supersprint system which ive been getting grief when travelling to track days ( from scotland). Particularly croft and oulton.
Ive got a lightweight racing back box, and what i think is an unresonated x pipe centre section, and normal front cats. Am not 100% sure re centre section as not had a look and not an expert, but mechanic says is wide bore un silenced centre supersprint centre part.

How best to drop a few db?

I dont want to be sent home. Am sure will be fine, but have a few belgian trips, few oultons and dont want any hassle.

I,like the drone, but wouldnt miss it. Dont want to drop too many horse, or go to a huge expense.

Any thoughts folks?

Thanks,

Gav
