ETS V2 MaxFlow Header

From the factory standpoint, the OEM exhaust manifold is super durable and robust, but it leaves much more room for improvement in terms of performance. It is very heavy and limited with flow. 

ETS has designed a super performance unit with their V2 MaxFlow Header. This header combines smooth bends and durable stainless steel construction to allow for an unobstructed flow path for the exhaust gases to escape. This will increase both the horsepower and the torque while reducing the turbo lag. Additionally, the unequal length design will really promote that Subaru rumble.
