Overwhelming Low Exhaust Pressure - 50％ of Original Pressure
φ60 large diameter pipe and full straight structure reduce the exhaust pressure to 50% of the stock.
This significant exhaust pressure reduction enables the turbine to run smoothly from low RPM range, which results in the engine output increase in an entire speed range.
Also, this pressure reduction effect is enhanced as the tuning level becomes more advanced; the engine output can be increased to450ps without engine power-loss.

About
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.
