HKS 31019-AN013 Hi-Power Silent Exhaust System

The HKS Hi-Power Exhaust System combines race-proven engineering with street-friendly performance. Inspired by endurance and GT racing in Japan, this exhaust system features an innovative offset muffler and piping design that maximizes flow while minimizing restrictions. The straightest possible exhaust path eliminates unnecessary bends, delivering improved exhaust velocity and power gains throughout the RPM range.

Key Features:

• Race-inspired offset muffler design for maximum flow efficiency
• SUS304 stainless steel construction for durability and corrosion resistance
• Silent Hi-Power version with integrated inner silencer for reduced noise
• Optimized piping layout eliminates restrictive bends
• Enhanced exhaust velocity improves turbo spool and boost response
• High-RPM power gains for both turbocharged and naturally aspirated applications

For turbocharged vehicles, the large-diameter, smooth-flowing design increases exhaust velocity, resulting in improved mid-range boost response and stronger high-RPM performance. Naturally aspirated engines benefit from the increased flow capacity, especially as tuning levels advance. This JDM Special Order exhaust system delivers the perfect balance of performance and refined sound quality.
