    Flowmaster 817580 - Flowmaster dBX Series Exhaust Systems Details


    Flowmaster dBX Series Systems were carefully engineered on the dyno to improve on delivering more horsepower, torque, throttle response, and mileage. These stainless steel cat-back systems bolt to the factory flanged connection directly behind the catalytic converter and follow factory routing back into a dBX Muffler and out through a 304S stainless tip with laser-engraved logo. Producing a much richer exhaust note than factory components, this advanced exhaust system generates a very tolerable interior sound level while providing a deep, pleasing exterior tone. Designed as a true bolt-on system, it includes all the necessary hardware for simple at-home installation. Made in USA.

  • 409S stainless steel construction for maximum durability
  • Patented race-proven technology
  • Deep, distinctive exhaust note with moderate interior tone
  • Easy-to-install bolt-on design
