Heavy walled manifolds for improved durability. Manifolds are coated to resist corrosion and are pre-drilled for pyrometer probes. These units replace the old rusted and leaking stock exhaust manifolds that normally require extensive cleaning and machine work to be recovered from warping and distortion. The manifold set comes with both passenger & driver's side units and feed pipe mounting hardware. With the stock manifolds considered a maintenance item due to corrosion and leaking, this set is an excellent preventative replacement item whenever doing other engine work.
 
Manifold Gaskets are NOT included with the manifold
