EYES ON THE STREET
After some investigation, this is custom bike god Shinya Kimura of Chabott Engineering's very own Cortina. See his post about the exhaust falling off right after it left the track you PEEPed it at: http://shinyakimura.blogspot.com/2011/05/muttley-do-something.html
I've added the celebrity tag to this bad boy. I expected nothing less from Shinya.
I now need to PEEP a Chevy Celebrity to join the ranks with Shinya.
