Cat-Back Exhaust System

The Nameless Performance cat-back exhaust system is meticulously crafted for the 2015-2021 Subaru WRX and 2015-2018 Subaru STI, offering a configurable sound and performance upgrade. Built by enthusiasts for enthusiasts, this system utilizes 100% T304 stainless steel construction throughout, from flanges to tubing and hangers, ensuring durability and corrosion resistance. The system is hand TIG welded by experienced fabricators in the Pacific Northwest, adhering to high standards of quality. The design focuses on building optimal torque in the midrange and excellent horsepower across the mid to top end. It aims to reduce drone during cruising and hill climbing while producing an aggressive, sharp, and refined sound signature at full throttle. Installation is made easier with v-band clamps for connecting segments, and OEM-fit connections at all OEM connection points, ensuring compatibility with factory exhaust parts. The front connection is designed to bolt up to both factory diameter and 3" diameter downpipes without additional adapters. Buyers can customize their exhaust experience with several options. The midpipe offers a choice between a resonator for a smoother, more refined sound with fewer pops and crackles, or a non-resonated version for more aggressive tones. Muffler options include Muffler Delete (loudest), 4" Mufflers (midrange tone boosting, rasp-cutting), and 5" Mufflers (deep, warm tone with a bark at wide open throttle). Six different exhaust tip styles are also available to personalize the appearance. This product is built to order with a lead time of 3-4 weeks and is intended for off-road use only. All necessary hardware, gaskets, nuts, and bolts for connecting the axle-back portion to the mid-pipe are included.
