ISR Performance Exhaust

Let your Scion FR-S growl with an ISR Performance Exhaust. With an aggressive design and a throaty rumble, it’s easy to mistake this premium cat-back street exhaust as all bark and no bite, but this dog has teeth. Designed for higher airflow for your Scion FR-S or Subaru BRZ, you get lower pressure for increased horsepower where the rubber meets the road.


  • 2.5-inches of ISR Performance exhaust with eye-catching 4.5-inch tips.
  • Tigg-welded stainless steel manufactured to ISR’s stringent quality standards.
  • Dyno results don’t lie. 6.12hp and 4.37 ft/lbs of Tq. gained at 7,000RPM with the cat-back alone. 2.5- inch test pipe added 6.81hp and 4.86 ft/lbs of Tq.

    Bought this exhaust looking for something not too crazy loud and affordable. Also the horsepower gains were good compared to all the other exhaust on the market and for half the price. Highly recommend this exhaust. A+++
