Key Features & Benefits

• Silent Hi-Power Technology — HKS's proprietary internal muffler design reduces cabin resonance and drone while still delivering a throaty, performance-tuned exhaust note at higher RPMs.
• Direct Bolt-On Fitment — Engineered to factory mounting points on the GF-BNR34 chassis for a straightforward installation with no cutting or custom fabrication required.
• Performance-Optimized Flow — Mandrel-bent tubing and a free-flowing muffler core reduce exhaust back pressure, supporting improved power output and throttle response on the RB26DETT engine.
• High-Quality Stainless Steel Construction — Built with premium stainless steel for superior corrosion resistance, long-term durability, and a polished OEM-plus aesthetic.
• JDM Heritage Engineering — Developed and manufactured in Japan by HKS to meet the exact dimensional and performance tolerances of the Nissan Skyline GT-R platform.
• Refined Sound Profile — Tuned specifically to produce a deeper, more aggressive exhaust note compared to stock while remaining far more livable than race-spec systems during daily driving.
