The Borla unequal length header replaces the factory exhaust manifold on turbocharged Subaru boxer engines with 1.625 in primary tubes feeding a 2.25 in collector for more efficient exhaust gas flow. It is built from T-304 austenitic stainless steel with mandrel bends, CNC manufacturing and a unique stiffened flex joint for durability, and is made in the USA. It carries California Air Resources Board Executive Order D-276-12 for the applications that order covers. Gaskets are not included; reuse the original equipment gaskets or purchase them separately.
