Description
AVOTurboworld Exhaust Turbo Outlet STI VF36 37 & 49 Twinscroll Turbochargers – Fits JDM STI 2003-2019 Subaru Impreza WRX STi EJ20 EJ20 2003-
AVOTurboworld’s twin scroll front pipe has a separate cast section to maximise the wastegate and exhaust flow. The design parameters immediately after the turbocharger are critical not only for outright performance, but for optimum torque and turbo response. The optimum internal profiles cannot be achieved with twin pipes. It is cast in high temperature ductile iron which ensures optimum internal shape and maximum durability under high rpm, load and boost conditions. Ideal for the customer wanting to build his own exhaust system but requires the hard part off the back of the turbocharger already to go.
