A good and efficient downpipe is proven to be very effective for the Subaru Impreza (GR) WRX STI.
Here is yet another Subaru Impreza (GR) WRX STI installed the SUPERCIRCUIT Catless Downpipe for better and unrestricted exhaust flow, hence faster turbo spooling and higher engine output.
The turbo downpipe is located behind the intercooler of the EJ257 engine below, so the intercooler and all the pipes connected to it has to be removed during the downpipe installation.
The SUPERCIRCUIT Downpipe is fully made with grade 304 mandrel bent stainless steel pipes and is fully TIG/Argon welded on CNC machined stainless steel flange for direct bolt-on application.
The stainless steel turbo outlet flange is bolted onto the Subaru Impreza WRX STI factory stock turbo flawlessly.
It is also fully compatible with the Subaru Impreza WRX STI's factory stock cat-back exhaust system, no cut and weld is required during the installation.
