HKS Racing Cat Back Exhaust w/Titanium Tip - Subaru WRX / STi 2002-2007

  • Sku: 31008-BF004
  • Brand: HKS

Get that flagship flat 4 rumble with the HKS Racing Muffler. This muffler has been designed with minimal bends that help reduce exhaust turbulence under acceleration which promotes more horsepower, more torque, reduced turbo lag, and a better throttle response. The larger piping diameter combined with the racing style muffler produces an aggressive tone under boost, as well as under idle.

Exhaust hangers are welded onto the OEM locations so that this exhaust system becomes a direct fitment without the need for any further modifications. Gaskets, as well as hardware, will also be included to make this racing muffler ready for installation.
