  • Add a deep, pleasing performance sound to your Subie WRX or WRX STI sedan
  • Elimination of factory catalyst increases aggressiveness of exhaust sound and adds louder turbo sound
  • Straight through sound absorbing muffler produces a deep and refined performance sound from idle throughout the RPM range
  • Resist the urge to put your foot in it to keep the RPMs and sound levels lower
  • Wide open throttle increases exhaust loudness and tone to an aggressive performance sound
  • If deep performance sound that becomes louder as you increase your acceleration fits your desire, this is the system for you
  • MRT’s proprietary Drone Management System TM (DMS TM) includes a tuned resonance chamber specific to this particular cat-back performance exhaust system
  • DMS TM actively manages drone levels to increase the comfort of the driver and passengers inside the vehicle and provide a unique performance sound

  • Replaces the factory downpipe and eliminates the catalytic converter with larger 3-inch tubing resulting in the fastest possible turbo spooling
  • Larger diameter exhaust tube eliminates the initial restriction point after the turbo of the stock downpipe allowing exhaust gases to flow at a much more rapid rate
  • Mandrel tube bending provides for the smooth flow of exhaust gases
  • Straight through muffler design provides for maximum exhaust gas flow
  • Larger exhaust tube reduces weight and exhaust gas flow restrictions producing noticeable performance gains
  • Higher exhaust flow prepares for future performance modifications
  • Lighter weight assembly as compared to stock exhaust system improves all aspects of performance
  • Larger exhaust tube and lighter weight over stock exhaust system improves gas mileage fuel economy
  • Longer lengths of increased diameter tube of the turbo-back system means even more gas flow and performance improvements than an axle-back system

  • Quad 4-inch double wall, polished T304 stainless steel tips with beveled edges add style to your ride
  • If you prefer a blackout look for the exhaust tips, choose the matte black Cerakote finish
  • Great sound and great looks turn heads and get positive comments!
