The HKS Super Turbo Muffler Exhaust for the Nissan Skyline R34 GTT/GT (4-door models) delivers a refined balance between performance, tone, and everyday drivability. Designed by one of Japan’s most respected performance brands, this exhaust system enhances the RB25DET’s natural power curve by reducing backpressure and improving exhaust gas flow. The result is a noticeable gain in horsepower and torque—typically between 5 to 15 hp depending on supporting modifications—while maintaining the factory drivability and balance expected from an OEM-quality fitment.
HKS developed the Super Turbo Muffler to provide a deeper, more engaging exhaust note that emphasizes turbo spool and acceleration without overwhelming cabin comfort. With a carefully engineered straight-through internal structure, it delivers a throaty yet controlled sound profile that’s quieter at idle and highway speeds but comes alive under boost. The result is an exhaust that feels mature, performance-focused, and well-tuned for enthusiasts who want performance gains without excessive noise.
Constructed from premium S304 stainless steel, the HKS Super Turbo Muffler offers exceptional durability and resistance to corrosion, ensuring it withstands years of spirited driving and variable climates. The polished finish and large-diameter exhaust tips give the Skyline a distinctive performance aesthetic that complements its iconic styling. For ER34 owners seeking a genuine upgrade that delivers measurable performance, enhanced sound, and long-term reliability, the HKS Super Turbo Muffler Exhaust is the ultimate street and track-ready solution.
