Ultimate Racing External Waste Gate (EWG) Uppipe/Downpipe Recirc Kit | 02-14 WRX / 04-21 STI (10051)

STi (02-15+) / WRX (02-14) EWG Uppipe and Downpipe Recirculation Kit by Ultimate Raing

Achieve the rock-solid boost control of an External Wastegate, but without the added volume. Our 3″ Downpipe is segmented into two sections: Top and Bottom (just like OEM). The Top section of our downpipe will mate to our own 3″ Bottom section as well as the OEM Bottom section. The recirculation provision for the EWG Uppipe is plumbed into the Top section. For this reason, we have made the Bottom section of our 3″ Downpipe an optional component. By default, this recirculation kit comes with the EWG Uppipe and Downpipe Top section.

Wastegate Note

F38 wastegate comes with 1 Bar (14.5psi) spring by default. For a different spring rate, please contact us. Additional charges may apply for requested spring rates above 1 Bar. MV-S and MV-R wastegates come with all springs by default. Installed spring pressure sets the minimum boost pressure for your setup mechanically. A boost controller can be used to increase boost pressure above this level.
