Features & Benefits

• 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
• Optimizes performance - made to smooth the interior manifold surface and keep heat within the manifold, leading to higher exhaust velocity and optimal operation
• Improves appearance - coating is highly corrosion-resistant, maintaining like-new appearance for years while other cast manifolds show significant unsightly rust
