Carbon-Ti Exhaust
Special Edition HKS Carbon / Titanium Hi-Power Exhaust systems are available for certain popular applications. These exclusive versions of the Hi-Power Exhaust consist of a carbon fiber wrapped stainless muffler shell, a 120mm titanium tip, and polished stainless steel piping.

Drager Exhaust
HKS Super Drager Exhaust systems incorporate a polished seamless-shell stainless-steel muffler assembly. All Drager systems utilize mandrel bent piping from 60 to 95mm in diameter and a 106 or 130mm Drager tip, depending on the application.

Drager II Exhaust
The new Drager II series, an evolution of the Original Super Drager, incorporates a new slim-line muffler assembly and utilizes a 120mm Drager tip that allows for an optional silencer insert to be used for additional sound dampening.

Hi-Power Exhaust
Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for both turbocharged and naturally aspirated applications. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.

Titanium Racing Muffler Exhaust
For extreme horsepower applications, the HKS Racing Muffler system, constructed of 102mm diameter stainless steel piping, a 170mm Titanium muffler assembly and a 115mm tip, is the lightest system and the highest flowing exhaust system HKS has to offer. FOR OFF ROAD USE ONLY

Turbo Exhaust
Specifically engineered for turbo applications that require greater flow capacity than naturally aspirated applications, Turbo Exhaust systems use a straight through design. The increased flow characteristics offer a gain in boost pressure, boost response, a broader powerband and increases overall peak horsepower. Performance increases vary by application, with average gains of 10-25 horsepower.

Turbo Upgrade Kits
HKS Full Turbo Upgrade Kits are designed to replace the entire factory turbocharger system with a high-performance turbo that maximizes the horsepower potential of the engine.

EVC (Electronic Valve Controller)
The HKS EVC is the 5th generation of HKS’s race proven Electronic Valve Controller series of boost controllers. The current version of the EVC is the first boost controller to feature integrated CPUs in each component (Display Unit, Control Module, and Stepping Motor) for more precise control, quicker response and improved boost pressure stability.
