HKS 31019-AN006 Hi-Power Cat-Back Exhaust System

The HKS Hi-Power Exhaust System is engineered with inspiration drawn directly from HKS's decades of experience in endurance and GT racing in Japan. Designed to deliver real performance gains for both turbocharged and naturally aspirated applications, the Hi-Power system features a race-inspired offset muffler and piping layout that maximizes exhaust flow while reducing restriction.

The system's design eliminates unnecessary bends to create the straightest possible exhaust path, resulting in greater flow efficiency and measurable power gains across the RPM range. For turbocharged engines, the large-diameter, smooth-flowing exhaust passages improve exhaust velocity for better mid-range boost response and increased high-RPM power output. Naturally aspirated applications benefit equally, with improved exhaust flow capacity that complements higher engine tuning levels.

Key Features:

• Race-inspired offset muffler design developed from HKS GT and endurance racing programs
• Straight-path piping layout minimizes bends for reduced back pressure and improved flow
• Compatible with both turbocharged and naturally aspirated engine configurations
• Constructed from SUS304 stainless steel muffler and tip assemblies for long-term durability and corrosion resistance
• Select applications available in Silent Hi-Power configuration, featuring an integrated inner silencer for reduced cabin noise
• Delivers high-RPM power gains through less restrictive exhaust path design

Built to the same exacting standards as HKS's Drager exhaust line, the Hi-Power series uses premium SUS304 stainless steel throughout the muffler and tip assemblies, ensuring lasting performance and a polished appearance. Whether used on a spirited street build or a track-oriented setup, the HKS Hi-Power Exhaust is a proven performance upgrade backed by HKS's motorsport heritage.
