BNM Performance Fab Equal Length Headers

These BNM Performance Fab headers are purpose-built for FA20 turbocharged Subaru engines, with direct compatibility for the VA WRX, SJ Forester XT, and Levorg. Whether you're working with a stock turbo or planning a bigger upgrade, these headers are engineered to let your setup breathe the way it should.

The factory manifold is a well-known restriction point in the FA20 platform, designed more for emissions compliance and cost-saving than performance. BNM’s header solution replaces this bottleneck with a high-flow, mandrel-bent, stainless steel design that dramatically improves exhaust gas velocity and turbo response. By streamlining the path from the cylinder head to the turbo, these headers help reduce backpressure, improve spool time, and unlock more power across the entire rev range.

These are true bolt-on components with no cutting, welding, or extra fabrication required. They retain all necessary mounting points and clearances for installation using factory hardware or high-quality aftermarket gaskets and fasteners. Whether you’re building a street car, weekend track car, or pushing for higher numbers on the dyno, these headers are built to deliver gains you can feel.

Like all BNM components, they’re hand-built in the USA with premium 304 stainless steel and thick, laser-cut flanges for long-term durability and leak-free sealing, even under sustained boost and high heat.

Gaskets and Hardware are NOT included. While compatible with the factory gaskets and fasteners it is always a good idea to replace these when installing new headers.

About BNM Performance Fab

BNM Performance Fab is built on a simple principle: do the job right, or don’t do it at all. Every part that leaves their workshop in the USA is hand-fabricated by a team that lives and breathes high-performance Subaru tuning.

This isn’t mass production. It’s precision fabrication using premium 304 and 321 stainless steel, shaped and welded with care, one piece at a time. From the first cut to the final weld, BNM components are crafted with a deep respect for quality and performance.

These parts are designed for builders who push beyond the factory limits. They’re made to take on high heat, serious boost, and the wear that comes with hard driving. Fitment is spot-on, with designs that install cleanly without modification or frustration.

BNM’s attention to detail is where it really shows. The use of thick, oversized, laser-cut flanges helps eliminate common problems like warping or exhaust leaks, even after countless heat cycles. Every weld, every cut, every finish is made to last.

Whether you’re upgrading a daily driver or building a full track car, BNM parts are built to support your goals now and into the future. They’re trusted by Subaru owners and engine builders who refuse to settle for generic bolt-ons. If your setup demands strength, reliability, and real craftsmanship, BNM delivers.
