Product Description
The PERRIN Single Exit Catback Exhaust (PSP-EXT-354BR) is a complete stainless-steel catback exhaust system made to significantly improve exhaust flow and create a deeper, more aggressive sound. It serves as a bolt-on upgrade that provides your 2022–2025 Subaru WRX with a sportier tone, better throttle response, and a sleek, performance-oriented rear exit look, featuring a sizable slash-cut tip.
This catback exhaust replaces the factory mid- and rear-section exhaust with a 3" mandrel-bent piping system made of sturdy 304 stainless steel, which enhances exhaust flow and reduces back pressure. A resonated mid-pipe helps lessen cabin noise at low RPM, but under heavy throttle, the exhaust produces a deeper, aggressive sound. The single 4.5" slash-cut tip exits perfectly and offers a motorsport-inspired look. It connects directly to your WRX using existing hangers and mounting points for easy installation.
According to dyno tests posted by retailers, the system delivers an approximate gain of 5–7 wheel horsepower (WHP) on a stock WRX tune, along with better turbo response and throttle feel.
Redline360 sells only genuine and authentic PERRIN Performance products.
