Product Description

The Borla 17217 Short Tube Header provides enhanced exhaust flow and throttle response for turbocharged Subaru models--from 2001 WRX to 2021 STI, plus turbocharged Legacy GT, Outback XT, and Forester XT variants. Constructed from T-304 stainless steel with CNC mandrel bends and a stiffened flex joint, it delivers a clean balance of power, refinement, and durability.

While CARB-exempt certification applies only to early WRX (2001-2003), the header is a bolt-in performance upgrade for newer Subaru models when used in off-road applications. Ideal for enthusiasts looking to extract more response and tone from their turbo powerplant, this Borla header offers proven quality, a million-mile warranty, and best-in-class fitment.
