Review HOOKER HEADERS Competition Full length Painted 5/8 Inch Primaries

The Hooker Headers 3901HKR Full-Length 5/8 Primary Exhaust Headers are a high-performance upgrade for your vehicle's exhaust system. These headers are designed to provide improved power and torque by optimizing the exhaust flow and reducing backpressure.

The Full-Length design ensures that the headers are of consistent length throughout, allowing for a smoother and more efficient exhaust flow. The 5/8 primary tubing diameter offers increased exhaust velocity and reduced exhaust gas temperature, which in turn leads to better fuel efficiency and increased horsepower.

Each header is precision-manufactured from high-quality 304 stainless steel, ensuring durability and resistance to corrosion. The 3901HKR headers feature a 1.625-inch inlet and 1.625-inch outlet, making them a direct fit for many applications without the need for additional adapters.

These headers come with 5/8-inch primary tubing, which is mandrel-bent to ensure a smooth and even bend radius. This results in a more efficient exhaust flow and a better fitment in the engine compartment. The exhaust gases exit the headers through 1.625-inch collectors, which merge the gases from the primary tubing into a single, larger exhaust pipe.

The Hooker Headers 3901HKR Full-Length 5/8 Primary Exhaust Headers are designed to be a direct replacement for factory exhaust headers, making the installation process straightforward and hassle-free. They come with all necessary hardware for installation, including new gaskets and nuts and bolts.
