HKS 31019-AN015 Hi-Power Cat-Back Exhaust System Stainless Steel

The HKS Hi-Power Exhaust System is engineered with direct inspiration from Japanese endurance and GT racing programs, bringing race-developed exhaust technology to street-driven vehicles. Designed for both turbocharged and naturally aspirated applications, the Hi-Power system features an offset muffler and straight-path piping layout that maximizes exhaust flow while minimizing restriction.

The system's core design philosophy focuses on eliminating unnecessary bends to create the straightest possible exhaust path. This results in reduced backpressure and improved exhaust scavenging, translating to measurable power gains across the RPM range — particularly at higher RPM where flow demand is greatest.

Key Features:

• Race-inspired offset muffler design for improved high-RPM flow and power
• Optimized straight-path piping eliminates unnecessary bends and reduces restriction
• Enhanced mid-range boost response and high-RPM power for turbocharged applications
• Increased exhaust flow capacity benefits naturally aspirated engines as tuning levels increase
• Available in Silent Hi-Power configuration on select applications, featuring a built-in inner silencer for reduced cabin noise
• Muffler and tip assemblies constructed from SUS304 stainless steel for corrosion resistance and long-term durability
• Aggressive yet refined exhaust note suited for street and track use

The HKS Hi-Power Exhaust is part of HKS's flagship performance exhaust lineup, sharing the same SUS304 stainless steel construction found in the HKS Drager series. It is an ideal upgrade for enthusiasts seeking a proven, race-heritage exhaust system with both performance and durability credentials.
