ADDED TO YOUR CART!
Maintain a factory original appearance, while adding a performance upgrade with these new exhaust manifolds. The increased performance and improved exhaust flow are a result of countless hours of testing and modifying the design of W-30/455 manifolds for small-block use. These manifolds feature a divided center port design as well as a large 2-1/4” outlet on the driver’s side. The smooth passenger’s side casting eliminates the need to plug the crossover pipe boss. Manifolds are sold as a pair and ready for direct bolt-on installation.
