HKS 31006-AN013 Hi-Power Cat-Back Exhaust System

The HKS Hi-Power Exhaust System combines race-proven engineering with street performance, delivering improved flow and power gains for both turbocharged and naturally aspirated applications. Inspired by endurance and GT racing in Japan, this exhaust system features an innovative offset muffler design that minimizes bends and creates the straightest possible exhaust path for maximum efficiency.

Key Features:

• Race-inspired offset muffler design eliminates unnecessary bends for optimal exhaust flow
• SUS304 stainless steel construction for durability and corrosion resistance
• Large-diameter piping increases exhaust velocity for improved turbo boost response
• Delivers mid-range boost improvements and high-RPM power gains on turbocharged engines
• Enhances exhaust flow capacity for naturally aspirated vehicles with performance tuning
• Polished stainless steel tip assembly for premium appearance

For turbocharged applications, the smooth, unrestricted exhaust path allows faster exhaust gas evacuation, improving turbo spool and mid-range boost response while maximizing top-end power. Naturally aspirated engines benefit from reduced backpressure and increased flow capacity, especially when paired with other performance modifications. The premium SUS304 stainless steel construction ensures long-lasting performance and maintains its appearance even in harsh conditions.
