High frequency sport sound right after acceleration. Not too loud while cruising. Quiet at idling. Exhaust system that links with drivers' mind.

The concept is the "light weight". It will give you the sporty look because of the carbon wrapped tip. The weight gets half of the stock muffler. We made each pipe and silencer lighter. The appearance is aggressive cannonball design and we wrapped it with carbon at the tail. It is a pure sport muffler which has improvement in weight and output performance.

High quality sound. Sport exhaust system with reduced noise level. In addition to high performance and sporty appearance, Silent Hi-Power muffler reduces noise level, making it the best choice for more mature enthusiasts. The Silent Hi-Power mufflers are made of SUS304 grade stainless steel for high lustre and durability. HKS has introduced a "Silent Chamber" for specific applications. The Silent Chamber works to reflect sound waves created by engine to cancel each other out. This closed-end structure creates a high muffling effect with almost no effect on performance.

The real street sports muffler. Hi-Power 409 mufflers offer a cost effective solution for your sports muffler needs. The rear section is made from SUS304 grade stainless steel for a high lustre finish and the piping section which is not visible once fitted is made from coated SUH 409, reducing the cost. SUH409 has other benefits such as being more resistant to thermal expansion and improved acoustic properties. SUH409 has the ability to absorb more sound than SUS304 which allows Hi-Power 409 mufflers to have a straight through design without fear of excessive noise.

The Ultimate High Spec Muffler Designed For 1000ps.  HKS has developed one of our most powerful muffler. It's for horse power of 1000. It's for R35 GT-R with HKS GT1000 RACING SPEC. We purely pursuit the exhaust efficiency for super low exhaust resistance pressure. The RACING MUFFLER pipe diameter is 101.6 and didn't have to narrow down. It connects to the main pipe by changing from the 2nd catalyzer so that we didn't have to limit the diameter of the pipe because of the stock flange part.

HKS Exhaust technology, which is know-how of long time development, targets to pull out 100% engine performance with the exhaust manifold. A lot of different approach were tried for each vehicle to keep performance for middle rpm range and to improve horsepower at high rpm.

For further performance enhancement. Universal sport type catalytic converter that can be used various level of tuning cars. It is well balanced for high horsepower and high cleaning performance. Target Horsepower 500 - 600PS. It is well balanced for high horsepower and high cleaning performance. Oval and Round types are released for various vehicles. Oval Type can be used for D85 - D90 and Round Type can be used for D115. (Modification is required.) As they are universal type, flanges need to be welded.
