HKS Hi-Power 409 Exhaust - 1998-2001 Nissan Skyline Coupe
Product Overview: HKS Hi-Power 409 Exhaust - 1998-2001 Nissan Skyline Coupe is an exhaust-system component engineered to improve exhaust flow and deliver HKS-specific sound and packaging. This listing is structured around the exact HKS product/SKU so shoppers can match the component to the intended vehicle or build without relying on a generic product-family description.
Driver Benefit: A freer-flowing exhaust can reduce restriction downstream of the engine while giving the driver a more purposeful exhaust note and a performance-oriented appearance.
Recommended Use: Best suited to street and track-oriented builds seeking an exhaust upgrade without changing unrelated engine systems.
Technical & Fitment Notes
- Confirm piping/tip configuration, emissions-equipment compatibility, and any trim or drivetrain-specific fitment notes for the exact HKS part number.
- Exhaust sound and cabin presence vary with the rest of the exhaust system, engine configuration, and vehicle modifications.
- Original catalog note: Note: For 2 door. Tip Diameter (mm): 120 Pipe Size: 85 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.
Fitment and specifications can vary by HKS part number, model year, trim, transmission, drivetrain, and market. Confirm the SKU and application before ordering, particularly on modified vehicles.
