Doug's Long Tube Headers replace restrictive stock exhaust manifolds with long primary tubes designed to dramatically increase the flow of exhaust gasses, and reduce power robbing back pressure within the exhaust system. Allowing the engine to breathe more freely improves power and efficiency, making Doug's Long Tube Headers one of the most cost-effective modifications you can make to your vehicle.
The Long Tube Header is perfect for any high performance street or strip application. Each header is constructed from thick wall steel, and all come finished with Doug's beautiful ceramic coating for long-lasting performance.
