HKS 32003-KN002 Hi-Power Cat-Back Exhaust System

The HKS Hi-Power Exhaust System is a race-inspired performance exhaust designed for both turbocharged and naturally aspirated applications. Developed from HKS's extensive experience in endurance and GT racing in Japan, this system features an innovative offset muffler design and optimized piping layout that minimizes unnecessary bends to create the straightest possible exhaust path for maximum flow efficiency.

Key Features:

• Race-inspired offset muffler design reduces restrictions and improves exhaust velocity
• Optimized piping with minimal bends for straight-through exhaust flow
• SUS304 stainless steel construction for durability and corrosion resistance
• Large diameter piping enhances mid-range boost response on turbocharged engines
• Improved high-RPM power gains through reduced backpressure
• Polished stainless steel tip assembly for premium appearance
• Select applications available in Silent Hi-Power version with integrated inner silencer

For turbocharged vehicles, the large-diameter, smooth-flowing design increases exhaust velocity, delivering better mid-range boost response and significant high-RPM power gains. Naturally aspirated engines benefit from the increased flow capacity, especially when paired with other performance modifications. The premium SUS304 stainless steel construction ensures long-lasting performance and resistance to corrosion and heat degradation.
