HKS Stainless Steel Header

Taking the same 4-2-1 design from the OEM exhaust manifold, HKS designed a Catless Stainless Steel Exhaust Manifold to increase the performance on your FR-S or BRZ. By removing the header's catalytic converter and increasing the exhaust diameter HKS increased torque in the mid range and power on the top end. Pair this with a free flowing front pipe and cat-back and you can expect even more power.
