HKS SUPER TURBO MUFFLER GRB/GRF is a premium cat-back exhaust system for 2008–2014 Subaru Impreza WRX and WRX STI hatchbacks. Engineered for improved exhaust flow and performance with a quiet, comfortable ride at low RPMs.

Features:

  • Vehicle Fitment: 2008–2014 Subaru WRX and WRX STI Hatchback
  • Piping Diameter: Straight 3-inch (75mm to 60mm) stainless steel piping to reduce back-pressure.
  • Tip Style: Twin split-rear exhaust tips, featuring 124mm polished stainless steel with burnt-blue titanium ends.
  • Sound Level: Moderate and sporty. Idles at around 66 dB and reaches about 88-90 dB under load, making it highly street-friendly without highway drone.
  • Construction: High-quality S304 stainless steel, built to resist weather and corrosion.
  • Downpipe: It bolts directly to the factory downpipe, though an OEM to 3-inch adapter may be required for some aftermarket downpipe setups.
