The HKS Silent Hi-Power Exhaust for the Nissan Skyline R34 GTT/GT (2-door models) offers a premium balance of performance, sound, and refinement for RB25DET-powered coupes. Engineered by HKS to deliver freer exhaust flow without excessive volume, this cat-back system is perfect for enthusiasts who want measurable gains in performance and sound quality while keeping their Skyline compliant with street noise regulations. The design prioritizes optimized exhaust gas velocity and reduced backpressure, allowing for quicker turbo response, improved mid-range torque, and a smoother powerband across all driving conditions.
Unlike loud or unrefined aftermarket systems, the HKS Silent Hi-Power produces a deep, mature exhaust tone with a clean turbo note that complements the RB25DET’s character. At idle, it remains subtle and civilized, while under load it delivers a throaty, performance-inspired growl that enhances the driving experience without becoming intrusive. This makes it ideal for both daily driving and spirited weekend runs, offering the perfect mix of stealth and sportiness.
Crafted from high-grade S304 stainless steel, the Silent Hi-Power exhaust is built to endure years of high-heat operation and resist corrosion in all weather conditions. The polished 120mm tips provide a sleek, factory-plus aesthetic that integrates seamlessly with the R34’s body lines. For those who demand authentic JDM performance and precision engineering, the HKS Silent Hi-Power Exhaust stands as one of the most refined upgrades available for the Nissan Skyline R34 GTT/GT.
