4 dollars on sale and some spray paint leads to a subtle tool box. It is much more subtle that the photos imply. Attachment is made to already existing mounting brackets. Standard metal banding material was cut, drilled, and bent around container for mounting bands. M6-1.00 pan head bolts for attachments.
Watertight to boot.
If it were done in silver it would just about match the plastic covering the muffler.
