HKS Replacement Ex. Manifold GDB EJ20 T/C

This HKS turbo exhaust manifold is constructed from durable SUS304 stainless steel with smooth bends and premium welds. It's a direct factory replacement designed to optimize exhaust flow, increase turbo spool, improve horsepower and torque, enhance throttle response, and reduce turbo lag, all while reducing weight. Its unequal-length design creates an aggressive exhaust rumble for a performance-oriented Subaru sound. Compatible with stock or aftermarket up-pipes using a 2-bolt flange. The kit includes two manifold gaskets, one up-pipe gasket, heat wrap, zip ties, and an O2 sensor plug for installation.
