Product Description   

The BOR17217 header is engineered to maximize exhaust flow and durability for Subaru WRX applications. Covered by California Air Resources Board Executive Order (E.O.) # D-276-12 for the 2001–2003 Subaru Impreza WRX, it provides a legal performance upgrade in approved regions. Designed with 1.625″ primary tubes merging into a 2.25″ collector, this header improves performance by efficiently channeling exhaust gases, resulting in better throttle response and overall power gains.

Constructed from premium T-304 austenitic stainless steel, it offers superior corrosion resistance and longevity compared to T-400 series alternatives. A stiffened flex joint ensures added durability under engine movement and heat cycles, while ultra-smooth mandrel bends and precision CNC manufacturing guarantee maximum flow and a perfect fit.

Gaskets are not included—OE gaskets must be reused or purchased separately. Like all Borla products, the BOR17217 is made in the USA and backed by the legendary Million-Mile Warranty, delivering long-lasting performance and the proven Borla quality trusted worldwide.
