HKS 2005-2007 Subaru Legacy GT Silent Hi-Power Dual Exhaust

The HKS Silent Hi-Power Dual Exhaust is a cat-back system built for the 2005-2007 Subaru Legacy GT sedan. It replaces the factory exhaust from the catalytic converter rearward to unlock more horsepower and torque while keeping a refined exhaust sound suitable for street use. Dyno-tested gains include +9 PS and +10 Nm over stock with a 27% weight reduction for quicker throttle response and better handling.

Key Features

  • Silent Hi-Power Design: Balances high-flow performance with low noise levels using advanced internal structure for sporty tone without drone.
  • Lightweight Build: 15.2 kg system versus 20.8 kg stock reduces unsprung weight and improves acceleration and fuel efficiency.
  • Mandrel-Bent Piping: SUS304 stainless steel tubing in φ60.5-80 x 2 φ50.8 configuration ensures smooth exhaust flow and maximum power delivery.
  • Titanium Muffler Tips: Dual polished φ120 mm tips add premium styling and heat resistance for long-lasting shine.
  • Precision Construction: Full SUS304 polished finish resists corrosion and maintains peak performance in all conditions.

Product Notes

  • Bolt-on replacement uses factory mounting points with included gaskets and clamps.
  • Pair with HKS intake or headers for additional gains.
  • Oversized item ships via ground freight for secure delivery.

Installation Notes

  • Professional installation recommended.
  • Requires cutting or removing stock resonators and hangers.
