The HKS Extension Kit for the RB26DETT is the ultimate upgrade for enthusiasts looking to optimize exhaust flow. Designed to bridge the gap between the turbine and the exhaust system, this kit reduces backpressure and significantly improves turbo spool and top-end power. Please note: this kit is specifically designed for standard configurations and is not compatible with the GTIII Sport Turbine Kit.
Upgrading your exhaust extension is a critical step in any serious engine build. By smoothing out the flow path immediately after the turbine, you allow the engine to breathe more freely, resulting in increased horsepower and torque across the RPM range. This component is built to handle the intense heat and pressure generated by high-boost RB26 setups. Whether you are building for the drag strip or the circuit, the HKS Extension Kit provides the flow efficiency required for peak performance. Upgrade your Nissan Skyline's exhaust system with confidence at GGCRACING.
