The exhaust system consists of a turbo header, and a complete 3" exhaust from down-pipe to muffler. Everything was fabricated by the folks at Alamo Autosports.  Several v-bands were utilized at convenient points to section the exhaust pipe into manageable pieces.  Everything in front of the flexi joint, which is directly under the rear transmission mount, was ceramic coated.  We also fabricated a "test" pipe to replace the Random Technologies 3" catalytic converter, on those special occasions. 

The turbo header is well documented in the link above, however, photos of the down-pipe and remainder of the exhaust system are posted below.
