RB30E 3.0L Performance Headers

The Hurricane Headers HU334STM is a performance header system engineered specifically for the Nissan Skyline R31 equipped with the 3.0L RB30E engine, covering model years 1985 through 1989. These extractors serve as an ideal replacement for the restrictive factory manifold, aiming to significantly boost performance. They feature a direct fit design that connects to the catalytic converter, with thick, machined flanges ensuring durability and a leak-free seal. The pipe configuration includes 42mm primary pipes, 51mm secondary pipes, and a 63mm flanged outlet, complemented by smooth merge collectors for improved scavenging and power delivery. Installation of these headers is intended to enhance fuel economy, increase exhaust flow, and improve torque and throttle response, making them suitable for street performance, off-road use, and general cruising. The product includes the Hurricane Header HU334STM itself. Additional components such as a header gasket (DSF059), replacement exhaust studs (TYS001), and a catalytic converter gasket (GMG093) are recommended for installation. Users should note that clearance may vary depending on engine mounts, steering components, and other aftermarket parts installed. Hurricane Headers provides a 2-year warranty on this product. Buyers are advised to check local regulations regarding emissions and roadworthiness compliance. For those undertaking installation, it is recommended to protect painted surfaces and wrap the headers during trial fitting.
