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.
