HKS GT Extension Down Pipe Kit For Nissan Skyline R32 R33 GTR All R34 GTR Non V-Spec 1418-RN005

Upgrade the performance of your Nissan Skyline R32 or R33 GTR with the HKS GT Extension Down Pipe Kit from Terra Firma. Designed specifically for R34 GTR Non V-Spec models, this kit optimizes the performance of your turbine while minimizing power loss.

Stock exhaust extensions merge the main port (turbine exhaust) and bypass port (wastegate actuator) in the turbine exhaust housing, causing interference between the exhaust streams. This interference leads to increased primary and secondary exhaust pressure, resulting in a drop in boost pressure and potential power loss.

The HKS Extension Kit overcomes these limitations by utilizing separate main and bypass ports. This design reduces exhaust gas interference, resulting in a smoother exhaust flow and improved performance. By reducing backpressure and enhancing boost response across the RPM range, the HKS Extension Kit maximizes the potential of your turbocharger.

With the HKS Extension Kit, exhaust gas interference is prevented through the use of 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 improving exhaust flow. The main pipe's diameter is enlarged at the turbine outlet to minimize swirl flow caused by exhaust gas interference. This prevents the rise of secondary exhaust pressure and stabilizes boost pressure, ultimately increasing engine output.

Constructed with high-quality materials, the HKS GT Extension Down Pipe Kit ensures durability and performance. The flange is made of high structural steel, while the piping is crafted from high heat-resistant and durable stainless steel (SUS304). Not only does this kit enhance performance, but it also improves the appearance of your engine compartment.

The HKS GT Extension Down Pipe Kit is compatible with both HKS GT Sports Turbine Kits and stock turbines, offering versatility for your upgrade options. However, please note that this kit cannot be used with the HKS GTIII Sports Turbine Kit.
