Featuring a high-performance sports catalyst and 60mm diameter piping, this HKS exhaust manifold allows a power gain of nearly 15hp at 4000rpm without sacrificing low-end torque on the Subaru BRZ ZC6 and Toyota GT86. Direct bolt pon upgrade for the FA20 engines, this HKS exhaust manifold made from T304 stainless steel was designed from a 4 in 1 unequal length structure in order to reproduce the sound of the typical Boxer 4 engine, abandoned by Subaru during their collaboration with Toyota due to the installation of equal length manifolds ex-factory.
