HKS GT Extension Down Pipe Kit For Nissan Skyline R34 GTR V-Spec 1418-RN011

Enhance the performance of your Nissan Skyline R34 GTR V-Spec with the HKS GT Extension Down Pipe Kit from Terra Firma. Designed to address the limitations of the stock extension, this kit optimizes the performance of your turbine, minimizing power loss and maximizing power output.

The stock extension merges the main port (turbine exhaust) and bypass port (wastegate actuator) in the turbine exhaust housing. This leads to interference between the exhaust streams, resulting in a drop in boost pressure and a loss of power. The HKS Extension Kit offers a superior solution.

By utilizing separate main and bypass ports, the HKS Extension Kit reduces exhaust gas interference and provides a smoother flow of exhaust. This effectively lowers backpressure, improving boost response across the entire RPM range. Even with the stock turbine, the exhaust gas interference can be prevented with a divider in the exhaust flange. The pipes connect to the lower part of the extension housing, where the exhaust gas pressure is lower, further optimizing performance.

The HKS Extension Kit features an enlarged diameter at the turbine outlet, reducing the swirl flow caused by exhaust gas interference. This prevents the rise of secondary exhaust pressure and stabilizes boost pressure, resulting in increased engine output. The flange is made of high structural steel for durability, while the piping is crafted from high heat resistant and durable Stainless (SUS304) for optimal performance and longevity. Additionally, these components enhance the overall appearance of your engine compartment.

Please note that the HKS GT Extension Down Pipe Kit is specifically designed for V-Spec models and cannot be used with the HKS GTIII sports turbine kit.
