GDB Super Turbo Muffler (models A-D) – 31029-AF001

GDB Super Turbo Muffler (models A-D) – 31029-AF001 The new HKS Super Turbo Muffler exhaust system for the Subaru Impreza GDB (Model E-G) is designed under the following specification: * Low back pressure with quiet sound levels * Suitable for stock power levels to high power vehicles with large turbo * Low sound level for comfortable street driving * Highlighting the distinct sound of the engine under acceleration The HKS Subaru Impreza GDB exhaust system is a 75mm diameter straight design. There are no narrow sections in the main silencer or tail pipe to reduce exhaust gas back pressure. The pipe layout is as straight as possible for ideal exhaust gas flow efficiency, while the inner slit shape uses silencer effect slits to reduce noise by approximately 2dB. Sound level and frequency were analyzed both inside and outside the cabin so that it does not prevent conversations and would not cause noise problem outside. In addition, low frequency “drone” noise was reduced to prevent uncomfortable noise inside and outside cabin. HKS Subaru Impreza GDB (Model E-G) Super Turbo Muffler exhaust Specification: Tail tip size: 124mm (Titanium) Main Pipe diameter: 75mm 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 Goichi 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. hks-company-info-2 Since its beginning, HKS has been committed to providing well-integrated, reliable, and environmentally sound performance systems. Mr. Hasegawa’s strong leadership, engineering genius, creativity and willingness to listen to customers are the pillars of the company’s success. Monitoring consumer reaction and input on issues pertaining to material quality, external appearance, sound quality, and of course, performance, HKS stays in tune with automotive enthusiasts’ needs. Moreover, HKS’ products are designed to be user friendly for easy installation. Today the automotive aftermarket industry is filled with start-up companies following in HKS’ footsteps. None however, can match the depth of engineering or manufacturing resources available to the talented, highly motivated and dedicated employees of HKS. For over 45 years, HKS products have been put to the test in drag racing, road racing, rallying, and top speed trials. HKS equipped vehicles have captured numerous racing championships and hold claim to a myriad of competition records using many “off the shelf”, race proven HKS components. As a result, HKS has been synonymous with “performance” in the automotive aftermarket industry for the past 40+years.
