HKS 31019-AM006 Hi-Power Silent Type-S Cat-Back Exhaust System

The HKS Hi-Power Silent Type-S Exhaust System delivers race-inspired performance engineering for street applications. Developed from HKS's extensive endurance and GT racing experience in Japan, this exhaust system features an innovative offset muffler design and optimized piping layout that maximizes exhaust flow while maintaining refined sound levels.

Key Features:

• Race-inspired offset muffler design for improved exhaust velocity and flow
• Optimized piping with minimal bends for straightest exhaust path and reduced restriction
• Silent Type-S configuration with built-in inner silencer for controlled sound output
• Premium SUS304 stainless steel construction for durability and corrosion resistance
• Enhanced mid-range boost response and high-RPM power gains for turbocharged applications
• Increased exhaust flow capacity benefits naturally aspirated engines with performance tuning

The Hi-Power Silent Type-S design eliminates unnecessary exhaust restrictions while incorporating an internal silencer to balance performance with street-friendly sound levels. The large-diameter, smooth-flowing exhaust path enables greater exhaust velocity, improving turbo spool response and delivering measurable power gains at higher RPM ranges. Constructed entirely from SUS304 stainless steel, this cat-back system offers long-lasting performance and maintains its appearance even in harsh conditions.
