Product Description

The MBRP S48003CF Cat-Back Exhaust System is engineered specifically for Subaru performance cars including 2011-2014 Impreza WRX and WRX STI, as well as 2015-2021 WRX and WRX STI models equipped with 2.0- and 2.5-liter engines. Constructed from mandrel-bent T304 stainless steel, this cat-back system improves exhaust flow over the factory setup while providing a richer, deeper street-tuned exhaust tone without excessive cabin drone. The dual split rear exit and 3.5" carbon fiber tips give your Subaru a striking performance-oriented rear appearance.

Installation is designed to be a direct bolt-on using the vehicle's OEM hangers and mounting points, requiring no cutting. The Street sound profile strikes a balance between spirited exhaust tone under throttle and comfortable sound levels for daily driving. Backed by a lifetime manufacturer warranty on materials and workmanship, the S48003CF delivers both durability and an engaging performance upgrade for Subaru WRX and WRX STI owners.
