Product Description

The MBRP S48073CF Cat-Back Exhaust System is engineered specifically for the 2022-2025 Subaru WRX with the 2.4-liter horizontally opposed engine and AWD drivetrain.

Its dual split rear exit with quad carbon fiber tips gives the WRX a bold rear-end presence that matches its performance intent.

Installation is designed to be a straightforward bolt-on process that uses the vehicle's original hangers and mounting points, with no cutting required. The system provides a noticeable performance sound upgrade and improved throttle response with up to approximately 42 % greater airflow than stock.
