PRODUCT DETAILS
Product Overview
Upgrade your Subaru WRX or STi with the 2022–Present Subaru WRX STi Full Cat Back Exhaust System, designed for enthusiasts who demand performance, durability, and an aggressive tone. Compatible with all 2022, 2023, 2024, 2025, and 2026 Subaru WRX models, this high-performance exhaust system is engineered to replace the restrictive factory setup. Featuring a resonated mid-pipe and muffler delete axle-back, it unlocks horsepower, torque, and throttle response while delivering a deeper, sportier exhaust note that enhances the driving experience without excessive drone.
Crafted from T-304 premium stainless steel with a sleek anodized silver finish, this system ensures long-term resistance to rust, heat, and corrosion. The 3-inch to 2.5-inch mandrel-bent piping optimizes exhaust gas velocity, resulting in improved flow, sharper acceleration, and potential fuel efficiency gains. The system is topped off with double-wall, 4-inch round angle-cut tips, giving your Subaru WRX a race-inspired look that matches the performance gains.
Whether you’re daily driving or hitting the track, this exhaust system transforms your WRX with an upgrade you can hear and feel.
Package Included:
1 x Subaru WRX / STi Full Cat Back Exhaust System (Resonated Mid-Pipe + Muffler Delete Axle-Back)
All required hardware for direct bolt-on installation
Key Features
The Subaru WRX STi Full Cat Back Exhaust delivers a complete performance and sound transformation for your 2022–Present model. The factory exhaust is restrictive and limits your car’s true potential, but this system unleashes power and enhances tone.
The resonated mid-pipe ensures smooth flow and reduces unwanted drone for comfortable highway cruising, while the muffler delete axle-back provides a bold, aggressive exhaust note that perfectly balances daily driveability with track-inspired excitement. Designed with mandrel-bent piping, the exhaust maximizes flow efficiency, sharpening throttle response and improving power delivery.
Constructed from T-304 stainless steel, this exhaust system guarantees long-lasting performance, even under harsh conditions. Its anodized silver finish adds a premium look under the car, while the double-wall 4-inch tips bring a sport-focused, stylish upgrade to your WRX’s rear profile. For WRX and STi enthusiasts, this system is the ideal balance of power, tone, and durability.
