Hi-Power 409 Exhaust for R32 Skyline GT-R

The Real Streets 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 luster 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 can absorb more sound than SUS304, allowing Hi-Power 409 mufflers to have a straight-through design without fear of excessive noise.
