HKS 409 Hi Power
SUH409 (steel) components can be made lighter for weights comparing to our components made of SUS304 (stainless steel). Also, SUH409 has low coefficient of thermal expansion that improves the product quality and cost effectiveness.
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.
