FlowMaxx Cat-Back Exhaust System Quad Tip

The Rev 9 FlowMaxx cat-back exhaust system is engineered for the Subaru WRX VB chassis, specifically for models equipped with the FA24 2.4L turbocharged engine from 2022 through 2025. This system aims to enhance exhaust flow and sound with its performance-oriented design. The exhaust features 3-inch diameter piping that transitions to dual 2.5-inch piping before entering the mufflers. It culminates in a quad-tip configuration, with four 3.5-inch double-wall slant-cut tips that provide an aggressive aesthetic. The system is constructed from SUS201 stainless steel, which offers good heat and corrosion resistance for daily driving, though T304 stainless steel provides superior long-term corrosion resistance, especially in high-salt environments. No tune or ECU changes are necessary after installation. The inclusion of a resonator is intended to minimize exhaust drone, while the dual muffler design contributes to a street-friendly exhaust note. Rev9 designates this product for off-road and competition use. Fitment Note: While this exhaust is designed for the 2022-2025 Subaru WRX VB, users with the GT and TS trims should verify fitment before ordering. These specific trims may have a different rear bumper configuration that could affect installation. It is recommended to contact the seller for confirmation if you own a GT or TS model.
