Borla Atak Catback Exhaust 2022-2025 WRX

This BORLA® Cat-Back™ system is engineered specifically for the WRX with the 2.4L engine. Featuring a 3" diameter single-exit design, it incorporates BORLA’s Polyphonic Harmonizer technology, which uses multiple tuned pipes to blend exhaust notes into a deep, refined tone with the aggressive ATAK® sound profile—without cabin drone. The system exits on the passenger side and is finished with laser-welded muffler end caps for a precise look. An extended Polyphonic Harmonizer muffler core flows into a 4.5" brushed T-304 stainless steel tip, complete with a laser-cut BORLA® logo.

BORLA® Cat-Back™ exhaust systems are built on patented straight-through and multi-core designs that improve exhaust velocity for increased horsepower, sharper throttle response, and the signature BORLA® sound.

Constructed from premium T-304 stainless steel, this system offers superior strength and corrosion resistance compared to lower-grade alternatives. Smooth mandrel bends maximize flow, while precision CNC manufacturing ensures an exact fit and long-lasting performance.
