The HKS Carbon-Ti catback exhausts are exclusive Special Edition HKS Hi-Power catback exhaust systems. Also referred to as the HKS Carbon Titanium Hi-Power catback exhaust, these exclusive versions of the HKS Hi-Power catback exhaust consist of a carbon-fiber wrapped muffler shell, titanium tip, and polished SUS304 stainless steel piping for a stylish and aggressive look. Each HKS Carbon-Ti catback exhaust looks as good as it performs.

Inspired by GT racing in Japan, HKS developed its Carbon-Ti catback exhaust system with features found on racing exhaust systems. The HKS Carbon-Ti catback exhaust series incorporates a race inspired offset muffler and piping design, eliminating unnecessary bends for the straightest exhaust path. This less restrictive design allows the HKS Carbon-Ti catback exhaust to have greater exhaust flow and less back-flow pressure, enhancing higher-PRM power gains.

The HKS Carbon-Ti catback exhaust system can be used for both turbocharged and naturally aspirated car applications. For turbocharged applications, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles also benefit from greater exhaust flow capacity as engine tuning levels increase. Certain HKS Carbon-Ti applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler.

Like the HKS Hi-Power catback exhaust systems, the HKS Carbon-Ti catback exhaust systems are made from high-quality SUS304 stainless steel. Each HKS Carbon-Ti catback exhaust system features high-quality mandrel bent piping and application specific muffler assemblies.

Most HKS Carbon-Ti exhaust systems are complete catback units, which do not effect emission related hardware. Each HKS Carbon-Ti catback exhaust system is designed for a specific car application and can be bolted on out of the box, using factory mounting hangers.

Depending on the car application, certain HKS Carbon-Ti catback exhaust systems can have muffler tip size of 96mm, 115mm or 120mm in diameter and piping diameter size of 55mm to 95mm.
