I have a 99 Chev Tracker 2 door with the 2.0 l 4 cyl.  I presently have a cracked manifold gasket.  I am smelling exhaust fumes inside the truck as I drive.  I work for a Toyota dealership & the mechanics have told me that my manifold is cracked.  I have been searching for a header, but am having no luck trying to find one.  I have one on my 89 Tracker with the 1.6l.  A new manifold is $1500 cdn, or $750 used cdn.  I'm not interested in putting a used one on for obvious reasons.  I live in Winnipeg Canada & am in dire need of something.  No one here wants to run the risk of repairing this cast manifold.
If somebody could please point me in a direction to finding a header.  That would be greatly appreciated.
Thanks
