Key Features & Benefits

• Silent Hi-Power Technology – HKS's proprietary internal baffling design reduces interior cabin noise and drone while still freeing up exhaust flow for real power gains over the restrictive factory system.
• Bolt-On Cat-Back Fitment – Engineered to precise OEM tolerances for the BNR32 chassis, ensuring a straightforward, no-modification installation using existing mounting points and hardware locations.
• Premium Stainless Steel Construction – Built from high-grade stainless steel tubing and muffler canisters for superior corrosion resistance, long-term durability, and a polished, show-quality finish.
• Optimized Exhaust Flow – Larger-diameter piping compared to the OEM exhaust reduces back pressure, improving throttle response and mid-to-high RPM power delivery on the RB26DETT engine.
• Refined Street Character – Unlike full race exhausts, the Silent Hi-Power is tuned for a deep, aggressive exhaust note that remains comfortable during daily driving and highway cruising.
• HKS Heritage & Proven Performance – HKS has been at the forefront of GT-R tuning since the BNR32's introduction, making this exhaust a trusted choice backed by decades of engineering expertise on this exact platform.
• Direct OEM Replacement – Replaces the factory Nissan cat-back section entirely, providing a clean, factory-grade fit with no trimming, cutting, or custom fabrication required.
