Overview

Add a sporty sound to your 2022–2025 WRX with the PERRIN Single Exit Catback Exhaust. Featuring an all stainless‑steel design and a 4.5” slash‑cut tip for added performance and good looks! 

Power

Dyno testing has shown a gain of 5–7 wheel horsepower after installing the PERRIN Single Exit Catback. This increase has been consistent across stock vehicles and aggressively tuned Stage 1 cars. 

Sound & Tone

Our resonated system is designed to have a mellow, pleasing rumble at lower RPMs and light throttle. When driving vigorously, the system transitions into an aggressive tone that every sporty car needs. 

No Drone Zone

The PERRIN exhaust features a frequency‑reducing Helmholtz resonator to combat the naturally occurring resonance the exhaust produces. This unique, engineered chamber reduces the low RPM droning and booming without adding any restriction to exhaust gas flow. 

Full 3" Exhaust With Resonator

The OEM exhaust system uses restrictive 2.36” and 1.7” tubing along with baffled mufflers. In contrast, the PERRIN Single Exit Catback has a full 3” tubing design from front to back, allowing your engine to achieve maximum power output. 

Adjustable Tip

The oversized 4.5″ slash‑cut exhaust tip fills the bumper cutout, adding a purposeful, race car look. The distinctive adjustable tip design enables you to customize both the length it extends beyond the bumper and its rotation. 

Single Exit Style

The PERRIN Single Exit Exhaust is designed to maximize power without adding extra weight, all while maintaining a refined, not‑too‑loud sound. 

Construction

PERRIN exhaust systems are made entirely of 304 stainless steel. Other manufacturers may use cheaper 409 stainless steel which will rust and corrode over time. Our brushed 304 stainless steel has the best corrosion resistance and appearance after use.
