Just installed the SuperCircuit made 3.0" Downpipe to the Subaru Impreza S204 (GD) with a two-liter (EJ20) H4 engine capable of developing 324 PS (239 kW; 320 bhp) and a six-speed manual gearbox.
To access to the turbo and the downpipe, one must remove the top mount intercooler on the Subaru Impreza WRX STI shown below. We have done it numerous time, so it is no stranger to us here at SuperCircuit Exhaust Pro Shop.
The factory stock downpipe of the Subaru Impreza WRX STI S204 (rear) and the SuperCircuit stainless steel 3.0" mandrel bent catless downpipe (front).
The SuperCircuit downpipe is designed to be able to plug 'n play to the Subaru Impreza EJ20 turbo without any further modification.
This Subaru Impreza WRX STI downpipe is made with grade 304 stainless steel, CNC mandrel bent and TIG welded in-house by our master craftsmen here at SuperCircuit Exhaust Pro Shop.
