The "bling-bling" version of the HKS Hi-Power catback, the Carbon-Titanium Hi-Power has all the features of the regular exhaust: 75mm piping, a resonator, non-tapered piping, and an angled-exit muffler, but, as the name implies, the Carbon Titanium features a carbon-fiber wrapped stainless steel muffler with a titanium tip and full SUS304 stainless steel piping. The HKS Hi-Power Carbon Titanium's full straight, 3in piping and free-flowing muffler reduce backpressure and create significant performance gains while giving your WRX or STI a deep, throaty exhaust tone.

  • Increases horsepower and torque by providing an unobstructed exit path for the exhaust gases
  • Reduces turbo lag
  • Produces an aggressive exhaust note
  • 304 stainless steel construction
  • Carbon fiber muffler
  • 4.72inch tip size
  • 3" inch piping diameter
  • Exhaust hangers welded onto the OEM locations for direct fitment
  • Includes new gasket and hardware

Note: Are you using a stock j pipe or downpipe? If yes, you'll also need the GrimmSpeed Subaru Stock DP to Aftermarket 3 in. Catback Adapter, available to purchase separately.
