The GrimmSpeed 2022+ WRX Equal Length Header is a high-performance, durable upgrade over the OEM exhaust manifold, specifically designed to enhance the Subaru FA24 WRX twin-scroll setup. Its CNC-bent, single-piece runners eliminate weld points for uninterrupted flow, ensuring true equal-length performance and better fitment between the skid plate and oil pan. The 304 stainless steel cast collector optimizes runner spacing, while 1/2-inch thick CNC-cut flanges and 1.75” 14-gauge stainless steel tubing provide excellent sealing, durability, and longevity. This kit includes all necessary gaskets and hardware, delivering both aesthetic appeal and top-tier performance.

2022+ Subaru WRX (2.4L FA24)
