Want to make sure your new exhaust manifold performs better and lasts longer than the original? No need to buy a replacement and get it specially coated. This manifold comes with a specialized ceramic coating that more evenly distributes heat, both helping to prevent thermal cracking as well as enabling smoother exhaust gas flow.

Features and Benefits:

  • Improves appearance - coating is highly corrosion-resistant, maintaining like-new appearance for years while other cast manifolds show significant unsightly rust
  • Optimizes performance - made to smooth the interior manifold surface and keep heat within the manifold, leading to higher exhaust velocity and optimal operation
  • Premium replacement - this exhaust manifold features a specialized ceramic coating designed to improve durability and performance on select vehicles
  • Reduces future failures - by evenly distributing heat, coating reduces uneven hot and cold spots that lead to cracks, and decreases inconsistent expanding and contracting that leads to gasket failures
