T304 Stainless Catback Exhaust, Dual 4-Inch Mufflers, 3.5-Inch Tips

The Nameless Performance Catback Exhaust is a premium exhaust system crafted from T304 stainless steel with TIG-welded construction, manufactured in Woodland, Washington, USA. Designed to replace the factory system on the 2015-2021 Subaru WRX and 2015-2018 Subaru STi (excluding 2019+ STi models), it features dual 4-inch mufflers and dual 3.5-inch polished single wall tips for a deep, sporty exhaust tone. This cat-back system boasts a 3-inch primary circuit with flow-matched dual 2-inch secondary circuits, optimized for increased midrange torque and smooth flow. It is engineered to provide proven gains of +32 ft-lb of torque and +22 hp on EJ engines, while flow-balanced dual circuits help reduce low-frequency cabin drone. The exhaust utilizes latch-over V-band connections for secure, warp-resistant sealing and includes all necessary hardware for a straightforward bolt-on installation. This system offers a sportier sound profile and enhanced midrange torque with reduced cabin drone, making it an ideal choice for both spirited driving and daily use. It is specifically designed for the 2015-2021 Subaru WRX and the 2015-2018 Subaru STi. Please note that this exhaust system is not compatible with 2019+ Subaru STi models.
