Below is how the turbo outlet looks like after the factory stock downpipe is removed from the Subaru Impreza WRX STI (GVB) Sedan.
The Subaru Impreza WRX STI (GVB) factory stock downpipe with a huge catalytic converter vs. the SUPERCIRCUIT catless downpipe which is made with larger bore mandrel bent stainless steel pipes and fully TIG/Argon welded on CNC machined stainless steel flange for long lasting performance and perfect fitment.
At the top, the SUPERCIRCUIT downpipe is mounted to the turbo outlet of the Subaru Impreza WRX STI (GVB) Sedan and at the other end, it is compatible with the stock catback exhaust system.
This catless downpipe promotes better exhaust flow. It is dyno tested to provide plenty of low-end torque and high-end horsepower and ideal for ecu remapping/ tuning needs.
