Borla’s 2.5RS header is constructed from T-304 stainless steel to give you the best in performance and durability. The stock Subaru header is extremely restrictive and clearly built to save costs, not make power. The Borla header features nice, smooth mandrel bends with a much more effective layout which improves mid and high RPM torque and power over the factory setup. Borla’s header will increase low end torque and throttle response through out the RPM range. Borla products are backed by a million-mile warranty, so this is the only header you will ever have to buy for your Subaru.
