We know the performance gains that come from adding Nitrous are nothing short of phenomenal. This owner has included his Nitrous bottle in his styling look. The bottle is highly polished and neatly installed between the rear passengers. It at least gives the driver an excuse to only carry 3 passengers!
Speakers have also been installed to maximise the dead space between rear passengers. The driver can rear the nozzle to turn on the Nitrous when it is needed, not something that can be done when it is installed in the boot.
