HKS Hi-Power 409 Exhaust 1989-1994 Nissan Skyline GT-R R32 31006-AN012
The HKS Hi-Power 409 is a full cat-back exhaust system engineered for the 1989-1994 Nissan Skyline GT-R (R32 BNR32). It uses model-specific piping layout for the straightest flow path reducing restrictions and backpressure. Drivers gain a louder deeper exhaust tone with 3-inch diameter piping that supports higher RPM power delivery and quicker throttle response.

- Piping Construction: Coated SUH409 steel with protective finish handles exhaust temperatures while preventing rust
- Piping Diameter: 3 inches (80mm) expands flow over stock for improved scavenging and horsepower gains
- Tip Diameter: 5 inches (120mm) rolled oval tips provide visual stance and amplify sound output
- Flow Design: Vehicle-tuned mandrel-bent pipes follow the shortest route minimizing turbulence for efficient exhaust evacuation
