Borla Unequal Length Headers – 2002-2014 Subaru WRX, 2004-2021 STi, 2001-2014 LGT

Borla’s Unequal Length header is constructed from T-304 stainless steel to give you the best in performance and durability. The unequal length design will maintain that boxer rumble while the free flowing design will improve power and torque throughout the rev range, the piping is not too large to hurt low-end torque The Borla header is a great bolt-on solution. Borla products are backed by a million-mile warranty, so this is the only header you will ever have to buy. This header is designed to bolt directly to a stock or aftermarket uppipe; we recommend changing the gaskets for a leak-free installation.
