"High performance" is the concept of this full titanium muffer. When temperature of the pipe becomes more than 600°C , the color of the pipe changes as shown in the picture. * Advantex is a registered trademark of Owens Corning.

The durable full titanium exhaust system is lightweight, and it weighs 10kg lighter than stock exhaust system. As rpm goes up, the sound changes like racing sound. The piping layout has large radius to optimize exhaust gas pressure and temperature. Reduced exhaust gas pressure can handle even hard tunings. Dual layer tips prevent heat affection to bumper, and slits inside tips have noise reduction effect. After a lot of R&D, finally HKS' flagship exhaust system has been available with ultimate performance, sound quality, and appearance. * Sould level with Metal Catalyzer: R 91dB L 92dB.

HKS is perhaps the most known aftermarket brand in the world.

In October 1973, two talented and spirited young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not or would not produce.
Led by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Mr.Kitagawa, the two secured a capital infusion from Sigma Automotive Co., Ltd. (hence the name “HKS ”), and began tuning gasoline powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan.
A year later, Mr. Hasegawa designed and built the first aftermarket turbocharger for passenger cars and has never looked back.
HKS pioneered the Japanese aftermarket performance industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back fuel computers and sophisticated fuel management tools. Clearly HKS was Driving Performance trends for Japanese vehicles.
