I purchased my exhaust kit from Krage Motorsports and it came complete with everything I needed for the install.  I was very impressed with how correct all the bends were.  My only complaint was that the exhaust downtube and the muffler exit tube were painted black.  Other than that, the installation went pretty quick.

I started with restoring the exhaust manifold.  All the holes got retapped and new bushings for the heat riser were installed.

Then both the exhaust and intake manifolds got sandblasted and painted with heat resistant black paint.  Both were installed with a new gasket and hardware coated with anti-seize.

The heat riser was installed with all new hardware.  (I think I have installed this incorrectly - I'm still checking).

The Krage kit follows the factory installation exactly and includes the correct muffler.
