3-Inch Cat-Back Exhaust System

The Nameless Performance Catback exhaust system is engineered to enhance the performance and sound of your 2015-2021 Subaru WRX or 2015-2018 STI. This system utilizes 3-inch diameter piping, paired with 5-inch mufflers and double-wall polished tips, to deliver an aggressive exhaust note and improved flow. Constructed with quality materials, this catback exhaust is designed as a direct replacement for the factory system, aiming to optimize exhaust gas flow. The 3-inch piping diameter is a key feature for maximizing exhaust efficiency. Fitment is specific to the 2015-2021 Subaru WRX and 2015-2018 STI Sedans. However, it is explicitly noted as not compatible with the STI (SPT) dealer-installed exhaust systems.
