Heavy-walled manifolds for improved durability. Manifolds are coated to resist corrosion and are pre-drilled for pyrometer probes. These units replace old, rusted, and leaking stock exhaust manifolds that normally require extensive cleaning and machine work to recover from warping and distortion. The manifold set includes both passenger and driver-side units along with feed pipe mounting hardware. With stock manifolds considered a maintenance item due to corrosion and leakage, this set is an excellent preventative replacement whenever performing other engine work.
