HKS 31006-AM004 Hi-Power Cat-Back Exhaust System

The HKS Hi-Power 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 and piping design that maximizes exhaust flow and high-RPM power gains through a less restrictive, straighter exhaust path.

Key Features:

• Coated 409 stainless steel construction for durability and corrosion resistance
• Race-inspired offset muffler design eliminates unnecessary bends for optimal flow
• Engineered for both turbocharged and naturally aspirated applications
• Large-diameter piping promotes greater exhaust velocity and improved mid-range boost response on turbo applications
• Enhanced exhaust flow capacity supports increased engine tuning levels
• Precision-engineered for direct bolt-on fitment

For turbocharged engines, the Hi-Power Exhaust's smooth, large-bore design increases exhaust velocity, delivering better mid-range boost response and superior high-RPM power. Naturally aspirated vehicles benefit from the increased flow capacity, especially as engine modifications progress. The coated 409 stainless steel construction ensures long-lasting performance and resistance to the elements.
