About Subaru Exhaust Power Packages

Subaru WRX & STI Exhaust Power Packages

Everything you need to unlock real, measurable power from your Subaru WRX or STI — in a single package. Our Exhaust Power Packages pair a high-flow cat-back exhaust system with a COBB Accessport, giving you the hardware and the tune to back it up. No guesswork, no mismatched parts — just a proven combination that works.


What's in the Package

  • Cat-Back Exhaust System — A performance cat-back selected for your WRX or STI application. Engineered to reduce backpressure, improve exhaust flow, and deliver a refined, aggressive exhaust note without sacrificing street manners.
  • COBB Accessport — The industry-standard ECU tuning device for Subaru. Flash an off-the-shelf map optimised for your exhaust upgrade, monitor live engine data, and data-log your runs — all from a single handheld device. Compatible with WRX (EJ20, EJ25, FA20, FA24) and STI (EJ257) platforms.

Why Package Them Together?

An exhaust upgrade without a supporting tune leaves power on the table. The COBB Accessport allows your ECU to take full advantage of the improved flow from your new cat-back — optimising fuelling, ignition timing, and boost targets to extract every horsepower your setup is capable of. It's the most cost-effective first step in any Subaru performance build.


Packages are available for multiple WRX and STI generations. Select your vehicle application at the product level to confirm fitment. For custom tune recommendations or build advice, contact us before purchasing.
