GrimmSpeed Equal Length Header 2022+ WRX

The result of our hard work is one of the best looking, performing and most-durable header options in the Subaru aftermarket. The runners are CNC-bent and trimmed as a single piece with no additional welds to introduce points of failure or junctions that would interrupt flow, resulting in a truly equal-length header with almost no variance in runner bend angle. This is especially important for maximizing the performance of the 2022+ FA24 WRX twin scroll configuration. Our unique low restriction 304 Stainless Steel Cast Collector allows for the perfect runner spacing and angles necessary to obtain the equal bends and lengths of all the tubes. This is a major part of the GrimmSpeed Header’s ability to fit between the stock skid plate and the oil pan, while still providing the ideal performance from the rest of the design. The collector allows for more smooth and consistent flow compared to a welded variant which can have the flow interruption or structural failure that we see with other headers.

The Header flanges are CNC-cut and faced from a 1/2in thick piece of 304 stainless steel. This design is much thicker than OEM and allows us to ensure perfect flange flatness. The result is greater gasket sealing and ultimately increased performance and reliability. The exhaust runners are also made from thick 1.75" 14Ga stainless steel tubing for increased longevity and are welded both on the inside and outside of the flanges. This is an extra step in manufacturing that provides a rounded lip to improve flow from the flange through the runner.

Our header kit comes with everything necessary for install on your VB WRX, including gaskets and hardware. All of these things come together to make The GrimmSpeed Equal Length Header for the 2022+ WRX not only the prettiest on the market, but at the top when it comes to performance and durability.
