metallic tape for exhaust bling

[scoobie_paws]

Hi all, my end can has nfr use on it and I was wondering if anyone knows of what type of tape or sticker would cover it safely. For some reason it is written in between the rivet strap at the back of the can so wondered if I could wrap it as MOT man says what the can't see don't hurt ;-)
Can not loud so not problem there just don't want any issues with it if I get stopped for anything

Bike is so yellow and black so something that looks OK with that would be good.
Thanks
Mark
