I have a Borla system on order for my Basalt black cayman S. I am going to change the chrome tip section to black- flat or gloss- have not decided which.What finish works best for this application- black chrome- powder coat - ceramic?Any suggestions on a source for this coating? Has anyone used Jethot? The section is fairly large 21'w x 11" long x 5" high. The entire rear section is welded together and the tips are not removable. The Orange 911 in the home page has black tips. Any idea what finish ?? Thanks in advance
