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.
Designed for direct bolt-on application, the SUPERCIRCUIT Catless Downpipe is made with grade 304 mandrel bent stainless steel pipes and is fully TIG/Argon welded on CNC machined stainless steel flange.
It is bolted onto the turbo outlet at the top and fully compatible with the Subaru Impreza WRX STI factory stock catback exhaust system at the bottom. No further mod or weld is required during installation.
To purchase or to install the above Catless Downpipe made for the Subaru Impreza WRX STI 2.5 AT, please contact us or pay us a visit to our showroom in SS13 Subang Jaya Industrial Estate or the SUPERCIRCUIT authorized dealers nationwide.
