HKS Stainless Steel Unequal Length Exhaust Manifold 2006-2014 WRX / 2004-2021 STI / 2005-2009 LGT

This turbo exhaust manifold is crafted from durable SUS304 stainless steel, featuring smooth bends and premium welds for a direct replacement of your factory manifold. Engineered to optimize exhaust flow and increase turbo spool, it delivers improved horsepower and torque, enhances throttle response, and reduces turbo lag—all while saving weight. The unequal-length design also produces an aggressive exhaust rumble, giving your Subaru a more performance-oriented sound.

Designed for compatibility, this manifold works with the stock up-pipe or any aftermarket up-pipe that uses a 2-bolt flange. The kit includes (2) manifold gaskets, (1) up-pipe gasket, heat wrap, zip ties, and an O2 sensor plug for a complete, straightforward installation.
