Carbon infill panel for acrapovic

I bought a slip on exhaust from another member and am really pleased with the look and sound.
I've been trawling the internet to find an infill panel but drawing a blank?!
Can't seem to find one anywhere and when I click on the leovince site it only gives me an option to buy the CB1000 one. Does anyone have a link that they could share please?

 

austin racing makes an infill, but not carbon unfortunately.

 

Thanks for the reply, I'll have a look at their site
