Hexagonal Quad Tip Cat-Back Exhaust System

The STI Performance Mufflers are genuine factory-engineered exhaust components designed to replace stock mufflers on 2022-2026 Subaru WRX models. These units are crafted from 304-stainless steel, providing a durable and corrosion-resistant upgrade. The mufflers are finished with double-walled, hexagonal quad exhaust tips that are debossed with the iconic STI logo, offering a sportier aesthetic and a more aggressive exhaust note for your vehicle. The internal design is optimized to provide reduced back pressure, which enhances exhaust flow efficiency. Each kit includes both the right-hand and left-hand muffler assemblies. Installation is designed as a direct bolt-on process. Each kit includes the necessary hardware for a complete installation, consisting of two muffler flange gaskets, four 14mm self-locking nuts, and four 14mm exhaust bolts, ensuring a secure fitment without the need for extensive modifications.
