This HKS extension kit, designed for the VR38 engine of Nissan R35 GTR, fits as a direct replacement for the OEM downpipes in order to remove the primary catalytic converters for optimal exhaust flow. Installed between the turbos and the Y-pipe, these HKS downpipes, made of S304 stainless steel, have a high-flow structure and a diameter of 3" / 76mm, which allows for sufficient backpressure to maintain optimal response time.
