  • Add a deep, pleasing performance sound to your Subie WRX or WRX STI hatchback
  • 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

  • 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
  • Higher exhaust flow and lighter weight improves gas mileage fuel economy
  • Cat-back system eliminates the factory mufflers for added power and weight reduction
  • Longer lengths of increased diameter tube of the cat-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!

  • Industry exclusive 100% T304 stainless steel straight through mufflers
  • Constructed from corrosion resistant T304 stainless steel tube, the best quality stainless steel for exhaust systems
  • All component parts (hangers, clamps, bolts) are stainless steel
  • CNC mandrel bending technology for precise fit
  • Unique proprietary manufacturing and quality control process produces the highest quality constructed and best fitting exhaust in the industry
