HKS HI-Power Performance Exhaust System 1998 - 2003 Lexus GS300 / GS400 / GS430 Dual (Rear Section Only)

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.

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 applications are available in a Silent Hi-Power version which has an inner silencer built into the muffler. Like Drager Exhaust systems, Hi-Power Exhaust systems are made from SUS304 stainless steel muffler and tip assemblies. Depending on the application, Hi-Power muffler tips are 96mm, 115mm and 120mm in diameter, piping diameter ranges from 55mm to 95mm. Special Edition HKS Carbon Titanium Hi-Power Exhaust systems are exclusively available for certain popular applications. These exclusive versions of the Hi-Power Exhaust consist of a carbon fiber wrapped muffler shell, titanium tip, and polished SUS304 stainless steel piping.

A refined level of performance and driveability is available in the MEDALION TOURING.

The elegant, well defined appearance of MEDALION TOURING is mature, and matches the artistry of a tastefully built, highly tuned machine.

Using the all new 'continuous strand' ADVANTEX packing material technology, MEDALION TOURING achieves extremely high levels of exhaust system efficiency, while maintaining a street driveable, extremely low frequency and deep tone that is well under 93db for discreet sports driving.

This system requires no removeable silencer for under 93db operation at all rpms. The extremely deep, low frequency tone keeps in-cabin noise to a minimum.

The full SUS304 stainless MEDALION TOURING features a slim-line oval canister, and a special dual wall, angle-cut tip.

This premium quality system is for sports driving.
