      Description

      PREMIUM PERFORMANCE EXHAUST COMPONENT. The AFE 1-5/8" x 2-1/2" twisted steel long tube header enhances exhaust flow and boosts engine performance by replacing restrictive factory headers. It is designed to improve horsepower, torque, and throttle response while maintaining a factory-like fitment.

      CONSTRUCTION AND APPEARANCE. Crafted from mandrel-bent 304 stainless steel tubing, the header features a brushed finish for durability and corrosion resistance. The laser-cut flanges provide a precise, leak-proof seal, and the entire assembly is 100% TIG-welded to ensure long-lasting strength under demanding conditions.

      INSTALLATION. This header is engineered to fit stock locations using factory-style flanges, requiring no cutting, drilling, or modifications. Installation is straightforward for those with mechanical experience, allowing for a hassle-free upgrade.

      APPLICATION. This product fits the 2015 through 2021 WRX STI models, designed specifically to accommodate the factory exhaust system seamlessly.
